Subject: Make the post form's tag input a box with a folded list of chips

A checkbox per existing tag stops working once a blog has dozens of
them. The form is now one comma-separated box, prefilled with the
post's tags, and the blog's tags sit folded under it as chips; a small
script toggles a clicked chip in the box, and without it the chips are
a plain list to copy from.
