fix(crud): resolve poc_person_id and poc_event_person_id FKs correctly

The generic FK resolver derives the lookup table name from the field name,
so poc_person_id → 'poc_person' (no such table) — the random string was
passed straight to an INT column, producing a MariaDB 1366 error.

Adds table name overrides matching the existing address_location → address
pattern. Blocking LCI session POC assignment via V3 PATCH.
