fix: per-event delete button, Docker network default, polling interval duration parsing

- Add per-event delete button (trash icon on hover) in event log entries
- Set Docker network default to 'docker-watcher' in DB schema + migration for existing DBs
- Parse Go duration strings (5m, 1h) to seconds in settings UI, convert back on save
- Clear error when network is empty in deployer instead of hidden fallback
