Firefly-2032: Add direct-download capability to Job Monitor

Description

We add download buttons/functionality to the Job Monitor and the Info icon's Results tabs, including for multiple results (e.g. SPHEREx).

Builds

Firefly: https://firefly-2032-direct-download.irsakubedev.ipac.caltech.edu/firefly

SPHEREx: https://firefly-2032-direct-download.irsakubedev.ipac.caltech.edu/applications/spherex

Approach

Essentially, we add a new streaming API to Firefly, passing the data along to the browser. (For due diligence, I had Claude double check if any third party / standard Java libraries offered what we wanted out of the box or with less complication. Where we landed in this pull request is the most straightforward and suitable). We also add a read timeout to the remote request. If we leave it to 0, a remote that stops sending data without closing the connection would hang the download indefinitely.

Testing/Validation

Unit/integration tests added (integration tests using a simple http server and fakes).

To manually spot check in Firefly, we can create a job and download a file. For example:

1. From the landing page, select AllWise Cone Search at M101.
2. Click search.
3. Navigate to the Job Monitor tab.
4. Click the new download icon (blue arrow). This should create a download in the browser (visible in the top right of a Chrome window).
5. If we then select the ⓘ icon, and expand Results, we should see the download button there as well. See screenshots below.

New Download Button in Info -> Results Panel

To see the download buttons added to the Info icon's Results tab for multiple results, in SphereX:

1. Open the Spectral Image Search tab. Click the example NGC 3256 under the target box, then press Search.
2. In Results, select the checkboxes on 3 rows. Press Generate Download Script above the table, then Download Script in the Download Options dialog.
3. When the Information popup opens, it will show 3 download icons.
4. Open the Job Monitor tab. The row has Type SCRIPT. Its first icon, Show Download Requests, opens the same 3 download icons.
5. Click ⓘ on the SCRIPT row and expand Results. It should show the 3 download icons here too (this is new).

New Multiple Results Buttons in Info -> Results Panel

Remote server error (404) handled gracefully

The changes look good. I noticed that the vertical alignment is slightly off. Could you fix that before merging? Thanks.
