Added feature to filter on main view (frontend popup + merging functionality with backend function)

[choksis8168]

Description

This adds a feature to filter on main view. I added a "Filter" button on the side navigation bar which users can press in order to filter each column header by different values which includes entry fields for name and participants and numerical ranges for all count fields. Note that this doesn't include filtering by chat type since this was addressed in #6. This merges backend functionality with the filter_treeview function added in #4. Users can click "Clear filters" in order to get rid of all selections.
