feat(provider): support Codex subscriptions with ChatGPT sign-in (#2513)
* feat(provider): support Codex subscriptions with ChatGPT sign-in * style: format Codex live integration test * fix(provider): preserve Codex identity in temporary model tests * fix(web): portal provider selector without dialog overflow * fix(web): allow native scrolling in provider dropdown * fix(provider): surface safe Codex quota and upstream errors * fix(web): provide reliable Codex copy feedback in dialogs * feat(provider): confirm cascade deletion from edit dialog * fix(persistence): discard connections after failed commit * fix(web): polish provider loading and confirmation motion --------- Co-authored-by: dadachann <185672915+dadachann@users.noreply.github.com>

Network I/O never holds a DB transaction. A persisted CAS lease serializes refresh
