Avoiding concatenated strings

[comradekingu]

Strings like "Mode: %1$s" replaced with "Podcasts" "Audio" etc. potentially get shown the wrong way round (?) as edoM : oiduA, when it should be oiduA : edoM in RTL. or get translated without care to preserve gender/articles of the second word. The first word may also be different based on the second.

This became apparent in #1071 https://github.com/podverse/podverse-rn/pull/1071#discussion_r906719655

Fixed by adding a single string for each possible case.
