feat(fusion_clock): planning -> native data migration [A8]

post-migrate(19.0.5.0.0) -> fusion.clock.schedule._fclk_port_planning_data:
planning.role -> fusion.clock.role, employee default/allowed roles, and
planning.slot -> fusion.clock.schedule (local date+float, role map, posted
if published, open if unassigned). Guarded (no-op on Community), idempotent
(marker), per-row savepoints. Integration test runs on Enterprise clones.
