fix: login attempts keeps counting even after account is blocked

[aniebietafia]

This pull request to brints-estate-api includes changes to improve the handling of user login attempts and blocking logic. The most important changes include adding a return statement to prevent further processing when a user is blocked and resetting the login attempt count upon successful login.

Improvements to login attempt handling:

• brints-estate-api/src/auth/providers/login-user.provider.ts: Added a return statement to exit the function early if the user is currently blocked to prevent any further processing.

Enhancements to blocking logic:

• brints-estate-api/src/login-attempts/providers/login-attempts.provider.ts: Reset the login_attempts count to 0 when the user's block status is reset.

Code consistency:

• brints-estate-api/src/login-attempts/providers/login-attempts.provider.ts: Added a missing save operation for the user repository to ensure the user's state is consistently updated.
