WebDAV file picker search is not debounced from user input (debounced value always empty)

Issue Title

WebDAV file picker search is not debounced from user input (debounced value always empty)

Problem

In the WebDAV file picker modal, the search input state is not correctly connected to the debounced value used for filtering.

Current code uses:

const [filterText, setFilterText] = useState('');
const debouncedFilter = useDebouncedValue('', 500);So even though filterText updates on every keystroke, debouncedFilter always stays ''.

Impact

• Search/filter behavior is incorrect in the WebDAV file picker.
• Typed text does not properly drive filtered results.
• Users may think search is broken or inconsistent.

Root Cause

useDebouncedValue is called with a constant empty string instead of the actual input state (filterText).

Proposed Fix

Change debounce source from '' to filterText:

const debouncedFilter = useDebouncedValue(filterText, 500);## Expected Result

• Search input updates immediately.
• Filtering updates after debounce delay (500ms).
• File list filtering behaves correctly and predictably.

Start at the WebDAV file picker modal and inspect the useDebouncedValue call alongside the filterText state. Change the debounce input to the user-entered state, then verify that filtering updates after 500ms and that the file list reflects the search text.
