feat(mobile-upgrade): add IT0 App version management support

Add IT0 App as the third application in the mobile-upgrade frontend,
connecting to IT0's new version-service backend.

Changes:
- api-client.ts: added 'it0' to AppType union, APP_CONFIGS entry
  pointing to NEXT_PUBLIC_IT0_API_URL (default: it0api.szaiai.com),
  exported it0ApiClient instance
- version-repository-impl.ts: added it0VersionRepository instance,
  updated constructor client selection for it0, updated
  getVersionRepository() factory with switch/case
- page.tsx: added IT0 App to APP_LABELS, added emerald green toggle
  button in app selector
- upload-modal.tsx: fixed existing bug where parsePackage() was
  hardcoded to use mobile repository regardless of selected app;
  now uses getVersionRepository(appType) dynamically

Backend: IT0 version-service at it0api.szaiai.com/api/v1/versions
Env var: NEXT_PUBLIC_IT0_API_URL
