Fixed a security vulnerability in the API get_item handler where raw database records were returned directly to clients, potentially exposing sensitive internal data. The handler now validates the database record against the Item Pydantic model before returning it, ensuring only allowed fields are included in the response. Added a new test suite to verify this behavior and recorded the learning in the security journal.

Previously, the get_item handler in the API template returned raw database records directly to the client. This could expose internal or sensitive fields (e.g., admin notes, internal IDs) not defined in the public Item model.

This change ensures that retrieved items are validated against the Item model, which strips any extra fields before serialization.

Changes:
- Updated templates/api/handler.py to validate get_item results.
- Added tests/api/test_security.py to verify internal fields are stripped.
- Added security learning to .jules/sentinel.md.
Removed `.jules/sentinel.md` following PR feedback. Code changes for sensitive data exposure fix and associated tests remain.
