feat: dashboard OAuth provider management

Add OAuth provider management to the Hermes dashboard with full
lifecycle support for Anthropic (PKCE), Nous and OpenAI Codex
(device-code) flows.

## Backend (hermes_cli/web_server.py)

- 6 new API endpoints:
  GET /api/providers/oauth — list providers with connection status
  POST /api/providers/oauth/{id}/start — initiate PKCE or device-code
  POST /api/providers/oauth/{id}/submit — exchange PKCE auth code
  GET /api/providers/oauth/{id}/poll/{session} — poll device-code
  DELETE /api/providers/oauth/{id} — disconnect provider
  DELETE /api/providers/oauth/sessions/{id} — cancel pending session
- OAuth constants imported from anthropic_adapter (no duplication)
- Blocking I/O wrapped in run_in_executor for async safety
- In-memory session store with 15-minute TTL and automatic GC
- Auth token required on all mutating endpoints

## Frontend

- OAuthLoginModal — PKCE (paste auth code) and device-code (poll) flows
- OAuthProvidersCard — status, token preview, connect/disconnect actions
- Toast fix: createPortal to document.body for correct z-index
- App.tsx: skip animation key bump on initial mount (prevent double-mount)
- Integrated into the Env/Keys page

/**
* OAuthLoginModal — drives the in-browser OAuth flow for a single provider.
*
* Two variants share the same modal shell:
*
* - PKCE (Anthropic): user opens the auth URL in a new tab, authorizes,
* pastes the resulting code back. We POST it to /submit which exchanges
* the (code + verifier) pair for tokens server-side.
*
* - Device code (Nous, OpenAI Codex): we display the verification URL
* and short user code; the backend polls the provider's token endpoint
* in a background thread; we poll /poll/{session_id} every 2s for status.
*
* Edge cases handled:
* - Popup blocker (we use plain anchor href + open in new tab; no popup
* window.open which is more likely to be blocked).
* - Modal dismissal mid-flight cancels the server-side session via DELETE.
* - Code expiry surfaces as a clear error state with retry button.
* - Polling continues to work if the user backgrounds the tab (setInterval
* keeps firing in modern browsers; we guard against polls firing after
* component unmount via an isMounted ref).
