V57: UUID FK Column Repair

Re-runs the idempotent UUID FK column operations from V56 to catch any
columns that were missed when V56 was applied with an earlier version of
the UUIDFKColumns module.

Specifically fixes `phoenix_kit_role_permissions` which may be missing
`role_uuid` and `granted_by_uuid` columns if V56 was applied before
those entries were added to UUIDFKColumns.

All operations are idempotent — this is a safe no-op on databases where
V56 already created everything correctly.
