feat: grant acc_wheeladmin to staff ranks for the wheel prize editor

The wheel prize editor is gated on acc_wheeladmin (client Settings button +
server WheelAdmin{Get,Save}PrizesEvent). Upstream 008_soundboard_fortune_wheel
registers the key but only grants rank_7 (its 7-rank hotel). This portable,
idempotent migration grants it to the same ranks as acc_ads_background via
dynamic SQL over the per-rank columns — no hardcoded rank ids. Apply then
:update_permissions or restart.

+-- Fortune Wheel — admin permission grant (`acc_wheeladmin`)
+--
+-- Both the client (FortuneWheelView "Settings" button) and the server handlers
+-- (WheelAdminGetPrizesEvent / WheelAdminSavePrizesEvent, PERMISSION_KEY =
+-- "acc_wheeladmin") gate the prize editor on `acc_wheeladmin`.
+--
+-- The key itself is registered upstream in
+-- `Database Updates/008_soundboard_fortune_wheel.sql`, but that file only grants
+-- it to `rank_7` (its author's 7-rank hotel) and its ON DUPLICATE clause touches
+-- the comment only. So on a hotel with a different rank layout the key would end
+-- up granted to nobody useful. This file supplies the portable grant.
+--
+-- Idempotent + portable: registers the key as a no-op safety (in case 008 hasn't
+-- run yet) and grants it to the same ranks that hold acc_ads_background — the
+-- adjacent "manage room-ad furni" permission — with dynamic SQL over the per-rank
+-- columns, so no rank ids are hardcoded. If acc_ads_background is absent the JOIN
+-- matches nothing and the key stays ungranted (safe; the button just stays
+-- hidden until granted by hand).
+--
+-- After applying, reload at runtime with `:update_permissions` (rebinds online
+-- users to the fresh rank and rebroadcasts the permission map — no relog) or
+-- restart the emulator.
+
+-- 1) Safety no-op registration (008 is the canonical registrar). rank_* default 0.

+
+-- 2) Grant to the same ranks as acc_ads_background, portably.
