Admin: gestión de precios de los servicios de personaje

- lib/admin-prices.ts: PRICE_TABLES (rename/customize/change-race/change-faction/
  level-up/transfer -> home_*price), getAllPrices, setPrice (fila única: DELETE+INSERT).
- Route /api/admin/prices (POST, guard isAdmin). Página /admin/prices con
  AdminPricesManager (editar cada precio). Enlace en el dashboard admin.
- Catálogo Admin (precios + nombres de servicio).

Verificado: /admin/prices redirige sin permiso, API 403; setPrice escribe en BD
correctamente (probado con env cargado). Pendiente admin: sitios de voto, gold options,
moderación del foro.
