fix: remove deprecated X-Tenant-ID header from SDK requests

Tenant identity is now derived from OAuth2 client credentials on the
server side. The X-Tenant-ID header is no longer needed.

- Remove addTenantIdHeader method and all calls
- Remove X-Tenant-ID header from policy API requests

Part of #1488: Unify auth to OAuth2 Client Credentials (RFC 6749).
