Parse and consume the query before dispatch.

Line 921 passes the raw query string to handleGetPerformance. handleGetPerformance discards it at Line 971. Therefore, query parameters do not affect any REST response.

Parse the query once in handleRequest. Pass typed parameters to handlers that support query options. Consume the documented parameters in those handlers.

In `@visualization/WebServer.cpp` around lines 909 - 921, Update handleRequest to
parse the query string once before dispatch, then pass typed query parameters to
handlers that support options instead of forwarding the raw query. In
particular, change the handleGetPerformance call and its implementation so
documented parameters are consumed and applied rather than discarded, while
preserving existing behavior for requests without query parameters.
