// Shared helper to build Cloudflare API auth headers from a token entry.
// Supports both API Token and Global API Key formats.
//
// Token entry shapes:
//   { token: 'xxx' }                              → API Token (Bearer)
//   { type: 'global_key', email: '...', key: '...' } → Global API Key
//   'plain-string'                                  → API Token (legacy)
