[dataquery] Clear filters btn

[marandmart]

Brief summary of changes

Adds a "Remove all filters" button to the DQT filter step, allowing users to remove all chosen filters with a single action instead of deleting each filter individually. The users are prompted to confirm action to avoid issues with accidental clicks of the button.

Resolves #10634

Tested this on RaisinBread and it works well.

Checked both places the button renders. With a single filter it sits to the right of the "and"/"or" condition buttons, and with two filters it shows up in the query tree next to "Add and condition to group". Confirming clears everything and the match count goes back to the full set, cancelling leaves the filters alone, and there is no button when no filters have been added yet. Translations are in for all four languages.

One non blocking thing: the confirm dialog does not set focusCancel, so "Yes" is the focused button when the modal opens and hitting enter clears the filters. Nothing else in the repo sets it either, so this is not really on you, but it is the same pattern as #10306 which is open against the dataquery "Are you sure" modal. Might be worth adding focusCancel: true here so that issue has one less spot to fix, or just leaving it to be dealt with there.

@marandmart This is a new feature, can you change the PR to the main branch?

@HenriRabalais Closing this PR in favour of a new one based on the latest main branch. I applied the focusCancel: true there. The new PR is here: #11096
