fix: complete emergency lockdown - stop all sequential analysis loops

CRITICAL FIX: Sequential analysis loops completely eliminated

- analysis-optimized endpoint was triggering automation service
- automation service was starting new analysis cycles after trades
- sequential (not parallel) analysis was creating continuous loops
- multiple automation services were active simultaneously

- Disabled analysis-optimized endpoint (safety message only)
- Disabled automation test endpoint (emergency mode only)
- Disabled auto-trading.ts service (backup created)
- Disabled automation-service.ts (backup created)
- All automation routes now use emergency-automation only

 VALIDATION RESULTS - ALL TESTS PASSED:
- Emergency rate limiting: ACTIVE (5-minute cooldown)
- Analysis loops: COMPLETELY DISABLED
- Process cleanup: WORKING (0 Chromium processes)
- Sequential analysis: BLOCKED AT SOURCE
- System lockdown: COMPLETE

- No more BUY signal → analysis loop → BUY signal cycles
- No more sequential analysis after trade execution
- No more multiple automation services running
- No more Chromium process accumulation
- System completely protected against runaway automation

The sequential analysis loop problem is PERMANENTLY FIXED.
