[Admin Tools] SIS imports history and details screen

Problem statement:

Admins don't have visibility of the SIS import runs; the SIS import screen only shows the latest import and doesn't include the parameters used in the run.

The only way to access this data is via REST client querying GET /api/v1/accounts/self/sis_imports API.

Proposed solution:

Create a new SIS Import History screen, where admins can see the history of imports run. The screen will include a list with all the SIS imports, and allow users to drill down into each import to get the relevant run details/parameters, associated files (input and reports).

The data to be included is the same already exposed via the /api/v1/accounts/self/sis_imports API - the API is already there, just create the screen 🙂
