Debank Authentication

note: Two independent auth surfaces. The DeBank Cloud Pro API is api-key only (AccessKey header, no scopes, no expiry,
  no rotation policy published). DeBank Connect is a separate OAuth 2.0 authorization-code service on api.connect.debank.com
  that is NOT described by the published Swagger, so it was searched from the integration guide rather than derived.

- No PKCE support documented for the public-client case.
- The 401/403 responses are documented on the error-code page but absent from the machine-readable contract.
