Send logger message as part of query request

Currently, each explorer function sends a log request to the server to log out which user action is being executed. Since it is a separate request that is fire and forget (not awaited) the order the server actually executes the requests can vary. It could also transiently fail.

Instead, add a new header value that defines a "query name" to use in the logs. This will provide enough context for diagnostics, adds additional context for those explorer functions that execute more than one query, and removes a redundant request.

This header should only be added when the proxy server is used.

Start by locating the explorer functions and the proxy-server request construction, then compare the existing log request with the query request and its headers. Done means the query name is included in proxy-server logs through a request header, explorer actions no longer send a separate fire-and-forget log request, and direct non-proxy requests are unchanged.
