Add a client-side filter above the File Browser table. Typing reduces
the visible rows to files/directories whose name matches, plus their
parent folders. A folder whose own name matches keeps its entire
subtree, and opening a matching folder shows its contents unfiltered.
* 'f' focuses the filter input, like the search inputs on other pages.
* An attached X button clears the filter; disabled while empty.
* A collapse-all (angle double up) button closes all open folders,
clearing the ?folders= query param and deselecting hidden children.
* The filter row is right-aligned and double-width on desktop, and
fills a single row on mobile.
