fix(rest): parse where param in parseParams

[hugomeduarte]

What?

Parse the where query parameter when it is sent as a JSON string in REST API requests (e.g. ?where={"read":{"equals":false}}), so that the filter is applied correctly. When where is already an object (e.g. from bracket notation like the Admin uses), it is left unchanged.

Why?

In GET requests, all query parameters are strings. When the client sends where as a JSON string, parseParams did not parse it, so find (and count, delete, etc.) operations received a string instead of an object and the filter was not applied. The same pattern already exists for the data parameter; this adds the same for where.

How?

In parseParams, after the data block: if where is present and is a string, run JSON.parse(params.where) and assign the result to parsedParams.where. When where is already an object (e.g. from bracket notation), the condition is false and we do nothing, so existing behavior is preserved. Added tests for the string case, the object passthrough case, and invalid JSON (expect throw).
