Add quick 'Adjust' button to pending payments table rows

Each worker row now has an Adjust button (slider icon) that opens the
Add Adjustment modal with that worker pre-checked and their most recent
project pre-selected. Header Add Adjustment button resets the modal
to a clean state (no workers pre-checked).
