Kyle Pope 2f58282c31 M-01+M-03: Add input validation and extra=forbid to all request schemas
- Add max_length constraints to all string fields in request schemas,
  matching DB column limits (title:255, description:5000, etc.)
- Add min_length=1 to required name/title fields
- Add ConfigDict(extra="forbid") to all request schemas to reject
  unknown fields (prevents silent field injection)
- Add Path(ge=1, le=2147483647) to all integer path parameters across
  all routers to prevent integer overflow → 500 errors
- Add max_length to TOTP inline schemas (code:6, mfa_token:256, etc.)
