Wire controlled column filters and clear-filters button

buildTableColumns now attaches antd controlled filter props (via
buildColumnFilterProps) to columns marked filterable; filters state is
controlled via Table onChange. A 'clear filters' button in the search bar
resets all filters and is disabled when none are active. Filters and row
lock reset on search/clear.

Also renames the component module table-filters.tsx -> table-filter-ui.tsx
to avoid a same-base-name resolution collision with the logic module
table-filters.ts.
