test(intake-links): placeholders for owner actions (see note)

Phase 8a Task 18. Server Actions are exposed via Next's RSC
boundary, not as plain HTTP endpoints; reaching into them from
vitest is not worth the complexity for a single new action. These
tests assert the admin project page renders for the owner so the
absence of unit-level action coverage is explicit.
