test(concurrency): cover the prefs guards, the inventory lock, and the privacy re-check

Add interleaved-writer, tokenless-compat, and malformed-token coverage for the
notification-prefs, modules, coach-prefs, and mood-tag-layout write guards,
including the notification-prefs case where a stale web write must not revert
the app-managed medication flag. Pin the inventory PATCH and DELETE routing
through the advisory lock, and cover the insight-generation privacy re-check on
both the main commit and the reroll arm.
