## Issue
5219: Add content type and language filters to channel page
## Notes
There is a quirk in the dropdown (see 5542: Language filter doesn't reflect effective setting if language is outside of `SEARCHABLE_LANGUAGES[ ]`)
## Issue
Fixes 4524 `[mobile] in channel search not available`
## Changes
There are currently 3 wunderbars: (1) header (2) channel list (3) downloaded list.
The additional `wrapperStyle` in the header made it hard to find a solution that works for all 3, so I split 2 and 3 into `wunderbar__input--inline`.
