[CST][ENG] Update File Uploader to use the new `va-file-input-multiple` component

[pmclaren19]

Background Context

Initially created a bug ticket here for the Platform Design team to update the va-file-input component to allow for multiple files. They took this ticket and created three new tickets to cover this work:

• va-icon-button - #2641 (needed for file input)
• update file input - #2642 (needs to happen before multiple file input)
• multiple file input - #2643

This work has now been completed and we can update the file upload component that we are using in the CST on the Doc Request Page and Files Tab to use this new component va-file-input-multiple

Originally had created this ticket for us to do this work but that was with the intent that the platform design team would update the current component va-file-input. They have decided instead to create a whole new component called va-file-input-multiple.

New Feature

Update the AddFilesForm component that allows users to upload files to now instead us the component va-file-input-multiple . This component is used on the Files Tab and Document Request Form

Engineering

• We will want to update the component AddFileForms to use https://design.va.gov/storybook/?path=/docs/uswds-va-file-input-multiple--docs#additional-form-inputs

Out of scope

• Updating the AddFilesFormOld component that is only enabled when the feature flag cst_use_claim_details_v2 is disabled

Open questions

• Do we need to use a feature flag?
• Do we need to update the ask va page as well?

Thanks for the ping, @pmclaren19! I would definitely like to test this when we implement it.

Reviewed and added some updates to tasks during eng refinement.

Still awaiting updates from Platform.

It looks the bugs Peri filed and linked to above are Closed. So is this ticket unblocked now? I added the latest design mock to the Design section.

I also want to highlight a bug I noticed while looking at this in staging:

Repro:

1. User uploads a file (File 1)
2. Gray "attached" box (which we will be removing as part of this ticket) shows up, confirming that File 1 has been uploaded
3. User clicks "Change file" to replace File 1
4. User replaces File 1 with File 2
5. The gray "attached" boxes show up for both File 1 and File 2, even though File 1 is no longer attached.

I assume this would get fixed when we remove that gray box and replace it with the pattern from the design system. But wanted to document this just to be safe.
