Restore snapshot form for auth status JSON test so re-introducing an
env_dev_token field would fail the snapshot, and rename the ps test to
reflect that it proves FABRO_DEV_TOKEN is ignored rather than that auth
is generally required.

Persist dev-token credentials in auth.json alongside OAuth entries so CLI targets resolve credentials consistently across TCP and Unix socket flows.
Move install-time token minting to runtime storage, add auth login --dev-token, and refresh the embedded SPA after updating the stale dev-token hint.
Add the server-side CLI OAuth endpoints and token persistence needed to
mint JWT access tokens and rotating refresh tokens from the existing
GitHub web auth flow.
Add CLI auth storage plus `fabro auth login`, `logout`, and `status`, and
prefer stored OAuth access tokens when building target clients.
