refactor: replace jobs proxy with local controller and optimize model loading (#174)

* refactor: replace jobs proxy with local controller and optimize model loading

- Add local jobs controller that directly fetches upstream gateway with
  profile support and 30s timeout, replacing unreliable proxy catch-all
- Upstream errors (non-200) return 502 instead of leaking to frontend
- Switch loadModels() from fetchAvailableModels (slow, fetches all
  provider APIs) to fetchConfigModels (reads config.yaml only)
- Hide logo dance video in sidebar

* fix: resolve TypeScript errors from previous refactor

- Remove unused imports (danceVideo, useTheme) in AppSidebar
- Map ConfigModelsResponse.groups to AvailableModelGroup[] format
