Add native ChatGPT Web provider for Codex clients (#8949)

* Bypass proxy compaction for native Codex context

* Add native ChatGPT Web provider pipeline

* Add managed browser and tunnel deployment

* Add ChatGPT Web setup and doctor UI

* Document and test ChatGPT Web integration

* fix(security): register chatgpt-web-codex-doctor in LOCAL_ONLY_API_PATTERNS

The diagnostic route under /api/providers/{id}/chatgpt-web-codex-doctor
was not registered in the spawn-capable route guard. Adding it for
parity with the existing /login pattern.

* fix(providers): route chatgpt-web-codex admin routes through a service boundary

The provider CRUD/doctor routes imported chatgpt-web-codex helpers
(finalizeValidatedChatGptWebCodexSecrets, encode/decodeChatGptWebCodexSecrets,
getChatGptWebCodexDoctorStatus) directly from open-sse/executors/**, which
no-restricted-imports (EXECUTOR_IMPORT_RESTRICTION) forbids for src/app/**
files — executor implementations must stay behind an open-sse handler or
service boundary.

Add open-sse/services/chatgptWebCodexAdmin.ts as a thin re-export boundary
(mirroring the existing tokenRefresh.ts re-export pattern) and import from
there instead. No behavior change.
