FIREFLY-1919: Add support for UWS jobs that produce non-table results

[loitly]

This PR add the ability to handle UWS job results other than tables (e.g., images). It introduces dynamic loading based on MIME types and add support for multi-result jobs.
It uses the original search request to process the job, and a configured loader to load the results to the UI based on its MIME type.
In cases where a job produces multiple results, a new selection popup allows the user to choose which result to load.
