Rename EndpointParams procedures to commands for CQRS clarity

Renamed Insert/Update/DeleteEndpointParamsProcedure classes and
handlers to use the "Command" suffix (e.g., InsertEndpointParamsCommand)
for consistency with CQRS conventions. Updated all controller actions,
handlers, and tests to use the new command names. This improves
clarity and aligns naming with standard command patterns.
