Add device security tests and enhance device capabilities

- Introduced comprehensive tests for device security features including GetRemoteUser, SetRemoteUser, GetIPAddressFilter, SetIPAddressFilter, and more.
- Implemented mock server responses for various ONVIF device security SOAP actions.
- Added new types and constants for device services, capabilities, and network protocols in types.go.
- Enhanced existing tests for device services, discovery modes, and network configurations.
- Ensured proper handling of service capabilities and network protocols in the client.

+
+## Security & Access Control
+
+```go
+// IP address filter
+filter, _ := client.GetIPAddressFilter(ctx)
+client.SetIPAddressFilter(ctx, &onvif.IPAddressFilter{
+    Type: onvif.IPAddressFilterAllow,

+    Type: onvif.IPAddressFilterAllow,
+    IPv4Address: []onvif.PrefixedIPv4Address{
+        {Address: "172.16.0.0", PrefixLength: 12},

+    Number:                  2,
+    SpecialChars:            1,
+    BlockUsernameOccurrence: true,
+    PolicyConfigurationLocked: false,
+})
+
+// Password history
+pwdHistory, _ := client.GetPasswordHistoryConfiguration(ctx)
+client.SetPasswordHistoryConfiguration(ctx, &onvif.PasswordHistoryConfiguration{
+    Enabled: true,
+    Length:  5, // remember last 5 passwords
+})
+
+// Authentication failure warnings

+client.SetAuthFailureWarningConfiguration(ctx, &onvif.AuthFailureWarningConfiguration{
+    Enabled:         true,
+    MonitorPeriod:   60,  // seconds
+    MaxAuthFailures: 5,
+})
+```
+
+## Relay & IO Control
+
+```go
+// Get relay outputs
+relays, _ := client.GetRelayOutputs(ctx)
+for _, relay := range relays {
+    fmt.Printf("Relay %s: %s, idle=%s\n",
+        relay.Token, relay.Properties.Mode, relay.Properties.IdleState)
+}
+
+// Configure relay
+client.SetRelayOutputSettings(ctx, "relay1", &onvif.RelayOutputSettings{
+    Mode:      onvif.RelayModeBistable,
+    IdleState: onvif.RelayIdleStateClosed,
+})
+
+// Control relay state
+client.SetRelayOutputState(ctx, "relay1", onvif.RelayLogicalStateActive)   // ON
+client.SetRelayOutputState(ctx, "relay1", onvif.RelayLogicalStateInactive) // OFF
+```
+
+## Auxiliary Commands
+
+```go
+// Wiper control
+client.SendAuxiliaryCommand(ctx, "tt:Wiper|On")
+client.SendAuxiliaryCommand(ctx, "tt:Wiper|Off")
+
+// IR illuminator
+client.SendAuxiliaryCommand(ctx, "tt:IRLamp|On")
+client.SendAuxiliaryCommand(ctx, "tt:IRLamp|Off")
+client.SendAuxiliaryCommand(ctx, "tt:IRLamp|Auto")
+
+// Washer
+client.SendAuxiliaryCommand(ctx, "tt:Washer|On")
+client.SendAuxiliaryCommand(ctx, "tt:Washer|Off")
+
+// Full washing procedure
+client.SendAuxiliaryCommand(ctx, "tt:WashingProcedure|On")
+```
+
+## System Maintenance
+
+```go
+// System logs
+systemLog, _ := client.GetSystemLog(ctx, onvif.SystemLogTypeSystem)
+accessLog, _ := client.GetSystemLog(ctx, onvif.SystemLogTypeAccess)
+fmt.Println(systemLog.String)
+
+// System URIs (for HTTP download)
+logUris, supportUri, backupUri, _ := client.GetSystemUris(ctx)
+// Download via HTTP GET from returned URIs
+
+// Support information
+supportInfo, _ := client.GetSystemSupportInformation(ctx)
+fmt.Println(supportInfo.String)
+
+// Backup
+backupFiles, _ := client.GetSystemBackup(ctx)
+for _, file := range backupFiles {
+    fmt.Printf("Backup: %s (%s)\n", file.Name, file.Data.ContentType)
+}
+
+// Restore
+client.RestoreSystem(ctx, backupFiles)
+
+// Factory reset
+client.SetSystemFactoryDefault(ctx, onvif.FactoryDefaultSoft) // soft reset
+client.SetSystemFactoryDefault(ctx, onvif.FactoryDefaultHard) // hard reset
+
+// Reboot
+message, _ := client.SystemReboot(ctx)
+fmt.Println(message)
+```
+
+## Firmware Upgrade
+
+```go
+// Start firmware upgrade (HTTP POST method)
+uploadUri, delay, downtime, _ := client.StartFirmwareUpgrade(ctx)
+// 1. Wait for delay duration
+// 2. HTTP POST firmware file to uploadUri
+// 3. Device will reboot after upgrade
+
+// Start system restore (HTTP POST method)
+uploadUri, downtime, _ := client.StartSystemRestore(ctx)
+// 1. HTTP POST backup file to uploadUri
+// 2. Device will restore and reboot
+```
+
+## Error Handling
+
+All functions return errors that should be checked:
+
+```go
+info, err := client.GetDeviceInformation(ctx)
+if err != nil {
+    log.Fatalf("GetDeviceInformation failed: %v", err)
+}
+
+// Context timeout
+ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
+defer cancel()
+
+info, err := client.GetDeviceInformation(ctx)
+if err != nil {
+    if ctx.Err() == context.DeadlineExceeded {
+        log.Println("Request timed out")
+    } else {
+        log.Printf("Error: %v", err)
+    }
+}
+```
+
+## Best Practices
+
+1. **Always use context with timeout** for network operations
+2. **Check capabilities first** before calling optional features
+3. **Handle errors gracefully** - devices may not support all operations
+4. **Use TLS skip verify** for self-signed certificates: `WithInsecureSkipVerify()`
+5. **Check reboot requirements** when changing network settings
+6. **Backup configuration** before factory reset or firmware upgrade
+7. **Test on non-production devices** first
+
+## Common Patterns
+
+### Check if feature is supported
+```go
+caps, _ := client.GetCapabilities(ctx)
+if caps.Device != nil && caps.Device.Network != nil {
+    if caps.Device.Network.IPFilter {
+        // IP filtering is supported
+        filter, _ := client.GetIPAddressFilter(ctx)
+    }
+}
+```
+
+### Safe configuration change
+```go
+// 1. Get current config
+currentConfig, _ := client.GetNetworkProtocols(ctx)
+
+// 2. Modify
+newConfig := currentConfig
+newConfig[0].Port = []int{8080}
+
+// 3. Apply
+err := client.SetNetworkProtocols(ctx, newConfig)
+if err != nil {
+    // Restore original if needed
+    log.Printf("Failed to apply config: %v", err)
+}
+```
+
+### Batch operations
+```go
+// Create multiple users at once
+client.CreateUsers(ctx, []*onvif.User{
+    {Username: "user1", Password: "pass1", UserLevel: "Operator"},
+    {Username: "user2", Password: "pass2", UserLevel: "User"},
+    {Username: "admin2", Password: "pass3", UserLevel: "Administrator"},
+})
+
+// Delete multiple users
+client.DeleteUsers(ctx, []string{"user1", "user2"})
+
+// Add multiple scopes
+client.AddScopes(ctx, []string{"scope1", "scope2", "scope3"})
+```

+
+## Next Steps
+
+To complete the full ONVIF Device Management implementation, the following categories need implementation:
+
+1. **Certificate Management** (13 APIs) - For TLS/SSL certificate handling
+2. **802.11/WiFi Configuration** (8 APIs) - For wireless network management
+3. **Storage Configuration** (5 APIs) - For recording storage management
+4. **Geo Location** (3 APIs) - For GPS/location services
+5. **Advanced Security** (3 remaining APIs) - Access policies and hashing algorithms
+6. **DP Addresses** (2 APIs) - Discovery protocol addresses
+
+These can be added following the same patterns established in the existing implementation.
+
+## Server-Side Implementation
+
+Note: This implementation provides **client-side** support for all these APIs. For a complete ONVIF server implementation, you would need to:
+
+1. Create a server package that implements the ONVIF SOAP service endpoints
+2. Handle incoming SOAP requests and dispatch to appropriate handlers
+3. Implement the business logic for each operation
+4. Add proper WS-Security authentication/authorization
+5. Implement event subscriptions and notifications
+
+This is a substantial undertaking and typically requires:
+- SOAP server framework
+- WS-Discovery implementation
+- Event notification system
+- Persistent storage for configuration
+- Hardware abstraction layer for device controls
+
+## Compliance Notes
+
+The current implementation provides:
+- ✅ ONVIF Profile S compliance (core streaming + basic device management)
+- ✅ ONVIF Profile T compliance (H.265 + advanced streaming)
+- ⏳ Partial ONVIF Profile C compliance (missing some access control features)
+- ⏳ Partial ONVIF Profile G compliance (missing storage/recording features)
+
+For full compliance, certificate management and storage APIs should be implemented.
