Migrate accessories to user data

- Add user_accessory as the per-user accessory inventory table.
- Migrate old accessory wear records to user-owned accessory ids, including legacy common_accessory_m lookups for old installs.
- Allocate default accessories for newly created users and update accessory reads to use user_accessory at runtime.
- Validate accessory ownership when wearing accessories and keep existing accessory-based responses working.
