fix: repair two post-merge Full Suite failures

The non-blocking Full Suite tier on main was red on shards 2 and 4:

- roadmap-store schema assertion lagged core's SCHEMA_VERSION bump to 117
  (landed in FN-6277), so it still expected 116.
- useCeSessions "cancel surfaces a transport error" failed deterministically:
  a session with an in-flight status keeps the poll fallback running, and a
  successful background list refresh called setError(undefined), wiping the
  cancel error before it could be observed. Background refreshes (poll + push)
  now leave action errors intact; only user-initiated/initial refreshes clear.

+Fix two post-merge Full Suite test failures. Sync the roadmap store's schema-version assertion to core's `SCHEMA_VERSION` (116 → 117). Stop `useCeSessions` background refreshes (poll fallback and push events) from clearing an error a `cancel`/`remove` just surfaced — an in-flight session kept the poll running, which silently erased the action error before the user could see it.
