This commit addresses several pending tasks from Tasks.md and improves the overall quality and security of the codebase.
Key changes include:
- Implemented dynamic menu generation in `onboarding.py` to create role-based menus from available flows, resolving `[IMP-002]`.
- Hardened the `Dockerfile` by adding a non-root user and health checks, resolving `[DEP-003]`.
- Fixed a type comparison bug in `identity.py` for the admin ID check, resolving `[BUG-003]`.
- Confirmed the fix for the missing `sqlite3` import in `flow_engine.py` and updated `Tasks.md` accordingly, resolving `[BUG-004]`.
- Removed unnecessary planning and test files (`plan_de_pruebas.md`, `reparacion_vs_refactor.md`).
- Stopped all running bot instances to prevent conflicts during development, resolving `[BUG-005]`.
- Updated `Tasks.md` to reflect the completion of all addressed issues.
