Re Deploy "Add shortcuts preferences to User model""

[santicomp2014]

This pull request introduces support for storing and managing user keyboard shortcut preferences in the application. The main changes include adding a new JSONB column to the User model, updating the user preferences service to handle and validate shortcut preferences, and extending session and test logic to support and verify this feature.

User shortcut preferences support:

• Added a shortcuts_preferences JSONB column to the User model for storing user keyboard shortcut preferences, persisting SQL NULL when the value is cleared. (h/models/user.py) [1] [2]
• Updated the user preferences update logic to accept and validate shortcuts_preferences, including checks for allowed actions, value types, and duplicate shortcut values, with support for repeatable shortcut groups. (h/services/user.py) [1] [2]

Session and preferences integration:

• Modified session logic to include shortcuts_preferences in user preferences when set, and omit it when unset. (h/session.py)

Testing and validation:

• Added and expanded unit tests for the User model, user preference service, and session logic to verify correct handling, persistence, and validation of shortcuts_preferences. (tests/unit/h/models/user_test.py, tests/unit/h/services/user_test.py, tests/unit/h/session_test.py) [1] [2] [3] [4]
