fix(mongodb): skip SQL semantic diagnostics for MongoDB connections

MongoDB shell syntax like db.collection.find({}) was incorrectly
parsed as SQL, causing a "sql parser error" diagnostic in the editor.
Added MongoDB guards in shouldRunSqlSemanticDiagnostics and
refreshSemanticDiagnostics, matching existing Elasticsearch logic.

Also fix a pre-existing TiDB cloud URL param ordering test failure.
