mindesbunister f420d98d55 critical: Make health monitor 3-4x more aggressive to prevent heap crashes

PROBLEM (Nov 27, 2025 - 11:53 UTC):
- accountUnsubscribe errors accumulated 200+ times in 2 seconds
- JavaScript heap out of memory crash BEFORE health monitor could trigger
- Old settings: 50 errors / 30s window / check every 10s = too slow
- Container crashed from memory exhaustion, not clean restart

SOLUTION - 3-4x FASTER RESPONSE:
- Error window: 30s → 10s (3× faster detection)
- Error threshold: 50 → 20 errors (2.5× more sensitive)
- Check frequency: 10s → 3s intervals (3× more frequent)

IMPACT:
- Before: 10-40 seconds to trigger restart
- After: 3-13 seconds to trigger restart (3-4× faster)
- Catches rapid error accumulation BEFORE heap exhaustion
- Clean restart instead of crash-and-recover

REAL INCIDENT TIMELINE:
11:53:43 - Errors start accumulating
11:53:45.606 - FATAL: heap out of memory (2.2 seconds)
11:53:47.803 - Docker restart (not health monitor)

NEW BEHAVIOR:
- 20 errors in 10s = trigger at ~100ms/error rate
- 3s check interval catches problem in 3-13s MAX
- Clean restart before memory leak causes crash
