fix(gateway): skip media sidecar for unrelated HTTP routes

 - Discord/streaming: show live reasoning text in progress drafts instead of a bare `Reasoning` status line.
 - Doctor/status: warn when `OPENCLAW_GATEWAY_TOKEN` would shadow a different active `gateway.auth.token` source for local CLI commands, while avoiding false positives when config points at the same env token. Fixes #74271. Thanks @yelog.
+- Gateway/HTTP: avoid loading managed outgoing-image media handlers for unrelated requests, so disabled OpenAI-compatible routes return 404 without waiting on lazy media sidecars. Thanks @vincentkoc.
 - Gateway/OpenAI-compatible: send the assistant role SSE chunk as soon as streaming chat-completion headers are accepted, so cold agent setup cannot leave `/v1/chat/completions` clients with a bodyless 200 response until their idle timeout fires.
 - Agents/media: avoid direct generated-media completion fallback while the announce-agent run is still pending, so async video and music completions do not duplicate raw media messages. (#77754)
 - TUI/sessions: bound the session picker to recent rows and use exact lookup-style refreshes for the active session, so dusty stores no longer make TUI hydrate weeks-old transcripts before becoming responsive. Thanks @vincentkoc.
