feat: Adapt providers `disabled` property to match user applied filters

Some filters are only available for certain providers, the UI should give the user
a hint to what providers such filters are available in.

Currently, if a filter (date or person) is not support by an a provider, the provider is
blurred out in the places dropdown.
