feat: add Codex OAuth login and fix channel config display

- Add OpenAI Codex Device Code Flow login (backend polling + frontend modal)
- Codex provider integrated into preset dropdown (hides URL/API key fields)
- Sync provider model catalogs with Hermes system
- Fix channel config not displaying on first visit (wait for data load)
- Fix sidebar model list not refreshing after adding provider
- Add autocomplete="off" to API key input to prevent browser autofill
