🧹 chore(calendar): cleanup debug logs and stale comments

- Replace console.error with NestJS Logger in NetworkService
- Remove debug console.log statements from mana page and events store
- Remove stale TODO comment in ShareController (user.email already available)
- Update TODO comments to "Workaround" notes in EventContextMenu
- Fix port fallback in main.ts (3016 → 3014) for consistency
