Improve D-Bus notifications handling

Browse Source 
Make notifications clickable on Linux by assigning "default" action.
Don't react to unrelated notifications clicked by keeping track of qBittorrent notifications IDs and filter out unrelated ones.
Make D-Bus Notifications interface proxy class to be maintained manually and fix coding style in it.
Closes #9084.
PR #17282.
