Pull request overview

This PR extends the Review Helper API by adding a ReviewerStatus enum and corresponding fields to track the specific status of reviewers (e.g., blocking, accepted, rejected). The changes refactor existing schemas to use a common base class that handles user action fields, and adds support for compound acting_capacity values that can encode both the capacity and reviewer status.

Changes:

• Added ReviewerStatus enum with 8 status values (blocking, added, accepted, rejected, commented, accepted-older, rejected-older, resigned)
• Created UserActionBase schema base class with validation logic for acting_capacity and reviewer_status fields
• Refactored ReviewRequestCreate and FeedbackCreate schemas to inherit from UserActionBase
• Updated database models and routers to handle the new reviewer_status field
• Added Alembic migration to create the reviewer_status enum type and add columns to review_requests and feedback tables
