Add padding to overcome aiohttp 64KB buffer in HA Supervisor.
Problem:
- HA Supervisor uses aiohttp with 64KB StreamResponse buffer
- Small SSE events (~200-500 bytes) were buffered until connection closed
- Users saw all streams appear at once instead of real-time updates
Solution:
- Detect Ingress mode via X-Ingress-Path header
- Add 64KB SSE comment padding to fill proxy buffers
- Increase progress interval to 3 sec in Ingress mode (reduce traffic)
- Normal mode (Docker/direct) unchanged - works exactly as before
Traffic impact:
- Normal mode: ~17KB per scan (unchanged)
- Ingress mode: ~2-3MB per scan (acceptable for real-time updates)
