Implement statistics module with activity tracking and user statistics

[Day-fit]

This pull request introduces a significant refactor to the user identification system, transitioning from using usernames and numeric IDs to universally unique identifiers (UUIDs) throughout the authentication and user management services. The changes impact entity models, repositories, authentication flows, and event handling, ensuring greater consistency and scalability in user identification.

Core changes to user identification:

• The EncryptifyUser entity now uses a UUID as its primary key instead of a Long, and all related repository interfaces and service methods have been updated to use UUID for user identification. [1] [2]
• Authentication and principal classes (JwtAuthenticationProvider, UserDetailsImpl, UserPrincipal) have been updated to use UUID for user IDs instead of usernames or numeric IDs, including token subject extraction and principal name representation. [1] [2] [3] [4]

Service and controller updates:

• User cache and service methods now operate on UUID instead of usernames, including account deletion, fetching user info, and checking if a user is banned. Controllers have been updated accordingly to use the new API. [1] [2] [3] [4] [5]
• The login and registration flows now return and use UUIDs for user identification in JWTs and cookies, and provide a method for retrieving usernames by UUID. [1] [2] [3] [4]

Event and communication changes:

• Events and communication services now pass and handle UUIDs for user identification, including the UserReadyForSetupEvent and email verification processes. [1] [2] [3] [4]

Build and configuration updates:

• The Maven version for encryptify-auth was updated from 0.0.1-SNAPSHOT to 0.0.1.
• The .idea/compiler.xml was updated to include the encryptify-stats module and to rename an annotation profile. [1] [2]

These changes collectively improve the robustness and future-proofing of user identification across the authentication system.
