Updates the `db_tasks.md` file to reflect the new database schema and role-based permission system.
This change introduces:
- A new `vacations` table to track vacation requests.
- A new `permission_requests` table for hourly leave requests.
- A redesigned `users` table with more detailed employee information and a `role` column.
- A renamed and expanded `onboarding_data` table.
- An updated database interaction section explaining the `user`, `manager`, and `admin` roles.
Creates a new `db_tasks.md` file that defines the database schema for the bot.
This documentation includes table definitions for:
- `users`: To store user information.
- `permissions`: To manage user permissions for specific actions.
- `welcome_flow_data`: To store data collected during the `/welcome` onboarding flow.
The file also explains how the bot will interact with these tables to manage users, permissions, and the onboarding process.
