Two new weapons placed at free item slots so they never collide with
standard Season 6 items. The client name DB (Item_eng.bmd) is the source
of tooltip name/stats, so only free slots are usable for custom items.
Both seed paths are covered:
- Fresh DB: Weapons.Initialize() calls the new CreateImperialWeapons050().
- Existing DB: AddImperialWeapons050UpdateSeason6 (UpdateVersion 95),
applied from the AdminPanel Updates page, with an idempotency guard.
Imperial Sword is a Magic Gladiator weapon (copy of 0/28), Imperial Staff
is a Wizard weapon (copy of 5/31).
