Two upstream Pydantic ValidationErrors that took down whole list responses.
#704: Contact.birthday is declared str, but vobject parses BDAY as a
datetime.date — any contact with a populated BDAY broke nc_contacts_list_contacts
entirely. Add a field_validator(mode="before") that coerces date / datetime
to ISO strings. Strings and None pass through unchanged. Defense in depth:
existing call sites already coerce, but the model is now correct on its own
so any future code path that constructs Contact from raw vobject output
stays safe.
#728: Tables app v2.0.1 stopped emitting owner_display_name on the top-level
table payload (still present inside views via get_schema), so list_tables
failed for every user with a Pydantic ValidationError. Make the field
Optional[str] = None — captures the value when present, won't blow up when
missing.
Six new direct-construction unit tests in tests/unit/test_response_models.py
pin both fixes (date / datetime / str / None for birthday; with / without
owner_display_name for Table) so the regressions can't recur silently.
