Switch protocol dashboard to OAuth 2.0 write scope + image mirrors (#14052)

## Summary
- **OAuth 2.0 migration**: Replace deprecated `write_once` scope with
standard `write` scope for the Connect Audius Profile flow. Rewrites
`useConnectAudiusProfile` hook to construct OAuth URL manually with
PKCE, sign wallet signatures with ethers (instead of
`audiusLibs.web3Manager`), and exchange auth codes for tokens after the
popup completes. Removes all references to old SDK OAuth APIs
(`oauth.init`, `getCsrfToken`, `activePopupWindow`, `OAUTH_URL`).
- **Web app OAuth page**: Extends `write` scope to support
`tx=connect_dashboard_wallet` / `tx=disconnect_dashboard_wallet` params,
reusing existing `handleAuthorizeConnectDashboardWallet` /
`handleAuthorizeDisconnectDashboardWallet` handlers.
- **Image mirror support**: Adds `MirrorImage` component with 3-second
per-URL timeout fallback for profile pictures and trending artwork.
Replaces raw `<img>` tags and `backgroundImage` inline styles that would
stall on unresponsive content nodes.

## Test plan
- [x] Connect Audius Profile: click button → popup opens → authenticate
→ profile picture + name appear
- [x] Disconnect Audius Profile: click Unlink → popup opens →
authenticate → profile removed
- [x] Profile pictures load with mirror fallback (simulate slow node by
throttling network)
- [ ] Trending tracks/playlists/albums artwork loads correctly with
mirror fallback
- [ ] Wallet connection via Web3Modal still works (no regression)
- [ ] `npm run verify` passes in protocol-dashboard
