fix(hub): steady the show detail modal, and give a series its director

Opening a different season of the same show moved everything under the
synopsis, which is where the season control and the episode list are, so the
thing just clicked was no longer under the pointer.

- The synopsis is exactly three lines for a multi-season show, with a "read
  more" link floated into the third line box (-webkit-line-clamp only ever
  puts its ellipsis at the end of the last line and leaves no room after it).
  Clamped from above and pinned from below to the same number: a constant,
  not a range — a season summary runs two lines and the next one twelve, and
  a band still reads as a jump. Whether three lines is all of it depends on
  the modal's width, so it is measured in the browser and re-measured on a
  resize.
- The cast is clamped to two lines.
- SeasonMenu replaces SeasonTabs: the tab row scrolled sideways once a show
  had more seasons than fit, which is close to unusable on a phone. One
  trigger reading "Season 5 · 1997" and a menu of every season with its
  episode count, one row high whatever the season count.
- media_meta_resp.director was filled from the credits crew's job ==
  "Director", a movie shape. TMDB's aggregate tv_credits crew is routinely
  empty and never carries that job, so every show answered null and the modal
  dropped the line. It now comes from created_by on the show details. Cached
  show metadata keeps its null until TMDB_META_TTL_SECS expires or an
  operator re-matches.

The facts line is joined rather than concatenated (a title with no rating
used to open with " · ") and carries the show's own year next to the
director; the selected season's air year moved onto the picker.

test_video_detail_measured.py asserts rectangles through layout_probe.py, not
declarations: the picker's offset inside its own modal body is the same pixel
either way, the synopsis and cast heights, where the read-more link lands,
and the open menu at 320 px. Each measured block sits in a whole-pixel-height
container, or two identical layouts an eighth of a pixel apart round to tops
one pixel apart. test_tmdb_show_director.py covers the credit.
docs/mediacenter.md §10.4.
