feat: implement webhook action firing & fault tolerance for automations

Backend:
- HTTP client with 5s timeout, fire-and-forget webhook delivery
- Payload schema: {trigger_id, trigger_name, condition, blob_id, person, position, zone, dwell_s, timestamp_ms}
- 4xx response: disable trigger, set error_message, push WS alert to dashboard
- 5xx/timeout: log warning, increment error_count, do NOT disable
- error_count resets on first 2xx response
- POST /api/triggers/{id}/test endpoint with synthetic payload
- POST /api/triggers/{id}/enable clears error state and re-enables
- GET /api/triggers/{id}/webhook-log for last N firings
- Audit log via webhook_log table (migration_007)

Dashboard:
- Error badge (ERR) on trigger cards when error_message is set
- Disabled badge when trigger disabled due to 4xx
- Warning badge for transient error_count > 0
- Test Webhook button with real-time response display
- Webhook Log button showing last N firings
- Re-enable button to clear error state
