Introduces the DB-backed connection config for the uo-link sidecar (the
HTTP + WebSocket bridge to the ServUO shard) and a never-throw REST client,
mirroring the existing Discord-bot integration:
- uo_link_config singleton table (base/ws URL, AES-256-GCM-encrypted shared
token, protocol pin, enabled, and last-known status/plugin_connected/
last_event_at/boot_id mirrors for the admin panel).
- model/uoLinkConfig: getSafe (never returns the token — only hasToken),
getWithToken (server-side decrypt), save (blank token = unchanged),
recordStatus (mirror the sidecar's reported state).
- utils/uoLinkClient: never-throw fetch client returning {ok,data,status,
error}; Bearer token + X-UOLink-Version on every call; brief config cache;
helpers for health/char/roster/vendors/history/economy/link/towncrier.
- .env.example: UOLINK_BASE_URL/WS_URL/PROTOCOL defaults (token stays
admin-managed in the DB, never an env var).
