MPDX-9121 Add Mutations to MHA

[kegrimes]

Description

Add graphQL delete, submit, and duplicate mutations to MHA. Also, updates UI based on new figma designs.

This PR also addresses this issue:

• When we save the form, we need to alert the user (ex. the Goal Calculator shows a snackbar every time it sends a mutation to the server to keep the user informed that the form is autosaving)

Note: requestId is hardcoded for testing purposes. If you delete this request id, the code will need to be updated.

Testing

• Go to /reports/housingAllowance
• Create a new request, enter in values, submit request, and then cancel request
• Check that each mutation works as intended
• Check updated current approved mha card design

Checklist:
