chore(desktop): remove dev:desktop:remote proxy mode

Drops the VITE_REMOTE_API Vite-proxy path introduced in be8b099c.
The remote-backend proxy is no longer needed; direct dev via
VITE_API_URL covers every workflow we still support.

- remove dev:desktop:remote (root) and dev:remote (desktop) scripts
- revert electron.vite.config.ts to a flat config — no loadEnv, no
  per-route proxies
- simplify App.tsx: single apiBaseUrl/wsUrl branch, and
  DAEMON_TARGET_API_URL derives directly from VITE_API_URL
