fix: Session auth, sidebar toggle, and dependencies table

- Change session.cookie_samesite from Strict to Lax for Authelia compatibility
- Redesign sidebar toggle with separate collapse/expand buttons
- Add script to create missing ticket_dependencies table
- Add .env.example template
- Add check for missing .env with helpful error message
