feat: standardize field names and add flexible role_id handling for JWT compatibility

- Rename user_id → users_id across all models, handlers, services, and tests
- Add custom RoleIDs type supporting string/int/array unmarshaling (e.g., "1", 1, [1])
- Implement flexible JSON unmarshaling for JWT Claims to handle field name variants
  - Support both user_id/users_id and email/email_address field names
  - Enable role_id as string ("1"), int (1), or array ([1,2])
- Update AuthorizationContext to handle role_id type flexibility
- Add comprehensive logging to repository, service, and handler layers
  - Entry/exit logs with full context
  - Success (✓) and failure (✗) indicators
  - Step-by-step authorization flow tracking
- Add containsRole helper for multi-role membership checks
- Fix database queries: user_id → users_id, id → permissions_id
- Update all tests to use models.RoleIDs{} syntax
- Change GetRole middleware return type: string → []int
- Maintain backward compatibility with legacy JWT tokens

This change improves integration with external services (MIS) that may send
role_id in different formats and standardizes field naming conventions
throughout the authorization microservice.
