Subject: [PATCH] fix(frontend): restore project library manifest inside
 buildLoadPayload (P2.4)

The inline manifest-restore in the load .then was being tree-shaken out of the
lazy ProjectByIdPage chunk (the deployed bundle had the save wiring but not the
load). Move it into buildLoadPayload, which is an exported helper (used by tests)
so its body is never dropped. Reloaded projects now re-send their manifest.
