feat: Implement Phase 3 modules

- Implements placeholder logic for the `agenda`, `citas`, `equipo`, `aprobaciones`, and `servicios` modules.
- Integrates all new module functions into the `button` handler in `app/main.py` to make the bot's menus functional.
- Fixes a newline formatting bug in the text responses to ensure they render correctly in Telegram.
- Updates `tasks.md` to reflect the progress on Phase 3.
