Add tests for RequestPasswordResetHandler and fix test compilation errors

- Add comprehensive tests for RequestPasswordResetHandler covering success and error cases
- Fix timezone-related test failures after removal of User.Timezone field:
  - Remove Timezone assertions from login_user_test.go
  - Remove Timezone field from RegisterRequest in integration tests
  - Update ValidateRegistration test cases (no longer validates timezone)
  - Update migrations_test to check current user table schema
- Fix syntax errors in user_repository_test.go (duplicate closing braces on lines 114 and 210)
