v2.3.1: CDN redirect gateway, fix token username bug

Browse Source 
- Migrate patch downloads to auth server redirect gateway (302 -> CDN)
  Allows instant CDN switching via admin panel without launcher update
- Fix identity token "Player" username mismatch on fresh install
  Add token username verification with retry in fetchAuthTokens
- Refactor versionManager to use mirror manifest via auth.sanasol.ws/patches
- Add optimal patch routing (BFS) for differential updates
- Add PATCH_CDN_INFRASTRUCTURE.md documentation
