test: add e2e test for Ctrl+E clear filters with input filter stuck in Filtering state

Reproduces bug where pressing Ctrl+E to clear all filters while an input
filter has a value causes the table to get stuck showing 'Filtering...'
until the user clicks cancel or resizes the grid.

The root cause is a race condition: clearAllFilters() clears the grid's
quick filters and stops loading, but the input filter's debounced empty
update arrives later, calling startLoading('Filtering...') again. Since
the filters are already cleared, applyInputFilters() finds no changes
and never calls setState, so handleUpdate/stopLoading never fires."
