chore(streamline): Folders for frontend

[leeandher]

A little more structure, open to suggestions about it, but the long directory made it challenging to scan.

Be more aggressive! Some components in here might've been created to support the new issues design, but I'd be surprised if FoldSection could never be reused by another product (maybe Feedback would reuse that soon!)
For those types of things move them all the way up & out of any folder or sub folder called issues/ so other people can find them, but also the specific stuff that is left is easier to read through too.
