fix(workplans): restore identifiers for records already on central

A repo-wide re-key overwrote the identifiers of eight workplans that were
correctly registered, breaking their link to the live records. Restored by
matching the canonical record id against central's slugs.

Re-keying is only safe for records central does not hold.
