@DataJpaTest against real Postgres (never H2): required-field round-trip,
YEAR default, linked persons/documents, eventDateEnd null/range round-trip,
TEXT description with no length cap, both RANGE-invariant rejections, the
UNKNOWN-precision rejection (NOT_SUPPORTED so the constraint violation does
not poison the test transaction), version null-before-persist/0-after-save,
and a parameterized accept-side proving DAY/MONTH/SEASON/YEAR/APPROX all
persist. makeEvent() defaults createdBy/updatedBy to random UUIDs so every
red is red for the intended reason.
@SpringBootTest cascade guard: deleting a linked Person/Document via the
domain service drops the join row (verified by direct COUNT) and leaves the
event intact.
