Two bugs:
1. Python 3.12 name collision in schemas.py: `date: Optional[date] = None`
caused get_type_hints() to resolve the `date` type annotation to NoneType
(Optional[None]) because the field name shadowed the datetime.date import.
All *Update schemas were rejecting any PUT with a valid date. Fixed by
aliasing the import: `from datetime import date as Date`.
2. FastAPI validation errors return detail as a list of objects, not a string.
Passing that list to new Error() produced "Error: [object Object]". Fixed
in api.js to map the detail array to msg strings before throwing.
