Subject: [PATCH] feat: improve sorting functionality in collectionGetHandler

The code changes in `handler.go` modify the `collectionGetHandler` function in the API handler. The changes introduce a more robust sorting functionality by splitting the sort parameter by comma and appending each part to the `clearedSort` slice. This allows for multiple sort criteria to be applied.
