- 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.)
