test(settings): settingsGuard unit tests — tab gating scenarios

Extract guard logic to settingsGuard.ts for testability.
Router beforeEach keeps async config.load() wrapper, delegates to sync guard.
14 test cases cover system/fine-tune/developer gates across cloud/self-hosted/tier/GPU profile combos.
