kyber-server: read EA token from auth.toml instead of browser flow

Running kyber_cli get_token under sudo opens a broken browser OAuth flow.
Instead, read the token directly from ~/.local/share/maxima/auth.toml which
Kyber writes after a normal GUI login. If missing, show clear instructions
to run the AppImage as yourself first, then re-run the installer.
