Fix config endpoint to return wrapped { configured, config } response
that the web UI expects. Fix services handler to return stored version
with defaults applied.
New tests:
- GetGlobalConfig: wrapped response, empty/not-configured case
- GetGlobalSecrets: leaf redaction preserves structure, raw mode
- UpdateGlobalConfig: write and verify
- CloudflareVerify: no-token case
- Services: register, list, get, update, deregister, TCP passthrough
defaults, validation errors
15 new test cases, all passing.
