feat: single config point — VS Code extension syncs credentials to CLI store

- configuration-webview: call ConfigService.saveApiKey() on Save so the CLI
  global store (~/.config/n8nac/credentials.json) is populated automatically
- lib.ts: export ConfigService so the extension can consume it via n8nac
- base.ts: fallback to N8N_HOST / N8N_API_KEY env vars when Conf store is empty
  (supports env-based usage without `n8nac init`)

Users now only need to configure credentials once in VS Code;
`npx n8nac <cmd>` works without a separate `n8nac init`.
