fix: remove database from Git LFS and track directly

- Removed Git LFS tracking for nodes.db to fix Docker builds
- Docker was getting LFS pointer file instead of actual database
- Database is only 20MB, safe to track directly
- Updated .gitignore to allow nodes.db tracking
- This ensures Docker always gets the actual database file
- Includes trigger detection fix (webhook, cron, interval, emailReadImap)

Resolves issues where Docker images showed isTrigger: false for trigger nodes
