Remove CLABE resources following identify service cleanup

Task: Remove CLABE resources

Following the cleanup in the identify service (PR #274: https://github.com/cuenca-mx/identify/pull/274), we need to remove the corresponding CLABE resources from this repository to maintain consistency across services.

Resources to remove:

• CLABE resource endpoints (likely /clabes)
• CLABE creation/management functionality
• Any related CLABE generation methods
• Client methods for CLABE operations

Context:

The identify service removed the entire identify/resources/clabes.py file which contained:

• FastAPI resource endpoint /clabes
• Async create method for CLABE generation
• Integration with external CLABE generation services
