Add RSVP role synchronization and localization support for Discord

This commit introduces functionality for managing event-specific RSVP roles in Discord, including roles for "Registered", "Going", "Maybe", and "Not Going". The `RoleWorker` has been enhanced to handle these roles based on user registrations, with localization support for role names in Russian and English. Additionally, the database schema has been updated to accommodate new role types and actions, and the service layer has been modified to trigger role synchronization upon relevant event updates. Tests have been added to ensure the correct behavior of the new RSVP handling logic.
