FXMacroData accepts the key three ways and documents X-API-Key as the preferred
transport for server-side clients. The provider was appending it to the query
string instead, so the key was written verbatim into every proxy, CDN and server
access log along the request path, and into any local HTTP debug output.

Switch to a per-request header so the behaviour still tracks self.api_key rather
than freezing it into the session at construction, and leave headers unset
entirely when no key is configured.

Covered by three tests: the existing request test now asserts the header and the
absence of an api_key parameter, plus one that no parameter value carries the key
and one that no auth header is sent without a key. The keyless test clears the
environment, since otherwise an ambient FXMACRODATA_API_KEY would be picked up
and the assertion would pass for the wrong reason.
