fix(sync): heal missing idle config field on schema-migration upgrade (#9124)
A v18.14 snapshot (schema v2) lacks globalConfig.idle.isSuppressIdleDuring
FocusMode, which #8965 added as a required field without its own schema bump.
Upgrading bumps the snapshot onto the v2->v4 migration path, whose validation
gate — uniquely, the only validator that runs on the RAW snapshot before the
loadAllData reducer can backfill defaults, and the only one that is fatal
rather than repair-or-tolerate — rejects it. Hydration then aborts, recovery
refuses because a snapshot still exists, and the app boots to an empty store,
deterministically, every launch.

Two fixes:
- v2->v3 migration backfills the opt-in default (false) when the field is not
  already a boolean (never clobbering a real user choice), so the migrated
  snapshot validates and a clean v4 snapshot persists immediately.
- The migration-path state-validation gate is now non-fatal: on failure it
  rolls the on-disk cache back to the pre-migration backup (never persisting an
  unvalidated snapshot) but returns the migrated snapshot for reducer-healed
  hydration, instead of throwing into disaster recovery. Genuinely corrupt
  state is still caught at Checkpoint C and not persisted. Metadata-validation
  failures remain fatal.

Both paths are sabotage-tested to fail without their fix. A known follow-up
(noted in code) can persist a fresh snapshot after any migration-then-valid
hydration so the safety-net path converges in one boot instead of re-migrating
each launch for a not-yet-backfilled field.
