The phone says when a channel follows its folder (GRYT-1306)

[sivert-io]

Task: GRYT-1306. Server: Gryt-chat/server#207. Desktop: Gryt-chat/client#632.

The phone's half of folder permissions. The phone doesn't edit folders, so this shows what applies and stops a Save from undoing it by accident.

What changed

• Channel permissions says whether a channel follows its folder. ChannelScopeScreen reads followsFolder and folder from server:channels:scope. A following channel gets "Follows the Staff folder. Pick something here to give this channel its own permissions. You can change the folder's permissions in the desktop app." One with its own gets "Has its own permissions instead of the Staff folder's." and a Follow folder button, which sends server:channels:scope:follow and stays on the screen for the server's answer. An older server sends neither field, and the screen looks the same as before.
• Save stays greyed out for Custom until a cell changes. A channel following a folder with rules of its own shows them as Custom, and saving them unchanged would have given the channel its own copy.
• Folders the server leaves out need nothing new. flattenSidebar already draws only the folders it's sent, with their channels. The empty-folder hiding from GRYT-1305 stays for older servers, and the comments say so.

Editing a folder's permissions on the phone is GRYT-1348. The line above says where to do it for now.

Verified

npx tsc --noEmit, yarn test (827, with new cases for sameRules and describeFolderFollow) and yarn test:comment-length. Not run on a device or the simulator. The screen change is a line of text, one button that sends one event, and a helper with tests.
