Polls, quotes and edits from the composer

The composer can hold a poll instead of media (two to four choices, a
length, one choice or several), quote a post (offered on a card when the
server says the persona may quote it), and edit the persona's own post: its
words and warning come from /source, and saving keeps its media,
visibility and poll. A card's menu offers Edit and Quote, and now opens
sideways: upwards, the first card's menu was cut off by the top of the
feed. The e2e tests publish a poll, edit a post and quote it, each checked
on PrivaPub.
