feat: add auto-repair at vendor open

When 'Auto Repair' is enabled in Settings > Gameplay, all damaged
equipment is automatically repaired when opening any armorer vendor
(canRepair=true). The repair is skipped when no items are actually
damaged to avoid a pointless server round-trip. A system chat message
confirms the repair. Setting persists to ~/.wowee/settings.cfg as
auto_repair.
