Filters: made on /filters, applied by each card where it is

The persona's filters (PrivaPub's /api/v2/filters): made, given words and
whole-word rules, contexts, an action and an expiry on /filters (linked from
Settings), and deleted; posts filtered one by one can be taken out. Every
status says which filters it matches; each page tells its cards where they
are (home and lists, notifications, public feeds, the thread around the
opened post, profiles), and a card leaves its post out (hide), folds it
behind the filter's title with a way to show it anyway (warn), or blurs its
media (blur). The e2e test folds and then hides a post of the persona's own.
