feat(app,android,ios): status, season dropdown, watched ticks

A title page now says where the show stands as a chip beside the
quality marks: Airing with the day the next episode comes out, Finished,
Upcoming, On hiatus or Cancelled. The words come from
TitleDetails::status_label, which the bridge hands the phones as
TitleRecord.status; the airing note leaves the line of facts.

A show with more than five seasons picks its season from a drop-down
rather than a row of pills that ran off the page, and a watched
episode's still carries a tick in its corner as well as the mark at the
end of its row.
