[RFG 2023] Remove filtering from dashboard (once all the filter-using functionality has been moved)

[cielf]

Summary

Remove the filtering from the dashboard

Why

Once we've moved all the bits that are filtered, the filtering is redundant

Details

This can only be done after the reports that use the filtering are moved from the dashboard (see other RFG 2023 issues)

At that point there will be no dashboard elements requiring the filter.

Remove the filtering section at the top of the dashboard. Also remove the Items on hand information and the "Make a transfer" and "Make an adjustment" buttons

Criteria for completion

• filtering does not appear on the dasboard
• confirm all tests around dashboard filtering have been reworked to point to the moved cards
• test suite passes

Also use this as an opportunity to remove unused data queries from the dashboard controller.

Formally assigning @awwaiid because I know Brock's doing a last push to get all the dashboard items in place.

Done and done!
