feat: Implement conversational flow for proposals

- Implements a multi-step conversational flow for team members to propose activities using `ConversationHandler`.
- Enhances the `aprobaciones` module to allow the owner to approve or reject proposals with inline keyboard buttons.
- Integrates the new conversational and approval workflows into the main application in `app/main.py`.
- Updates `tasks.md` to reflect the completion of the `equipo` and `aprobaciones` modules.
