Fix content packs, seed the leaderboard, and add the missing site furniture

Naming
- "Typing Test" removed from the browser tab, the crate description and the
  READMEs. The scope outgrew it: solo practice, live races, code drills and
  adaptive weak-key training.

Content
- Movies was prose *about* film, not film quotes - the same mistake the
  programming pack had. Replaced with 28 attributed lines. New anime pack,
  28 lines across 24 series.
- This follows the model TypeRacer states outright ("type quotes from popular
  music, songs, anime, comic books and more"): short excerpts attributed to
  the work they came from. The scalable half of their approach is user
  submission with moderation, which is a feature this does not have yet.

Leaderboard
- An empty board tells a new player nobody is here. Bots now race the eight
  fixed-length leaderboard modes, seeded with a fortnight of backdated results
  on first run and one new result every 90 seconds after.
- They are ordinary users carrying is_bot, returned by the same query and
  labelled "bot" in the UI. Seeding a board is reasonable; passing synthetic
  scores off as human results is not, so the flag travels with the row.
- Seeding is checked per mode. A single result from the live ticker used to
  satisfy an "any bot results" guard and leave every other mode empty forever.

Stats
- The per-key accuracy data Practice mode is built on was computed, used to
  generate text, and never shown. The screen now ranks your weakest keys with
  the error rate and pause length behind each one.
- Added recent form against your lifetime average, best accuracy, and tests
  this week.

Multiplayer standings
- Now place, racer, WPM, accuracy and time, with column labels - the columns
  TypeRacer and 10FastFingers both show.

Site furniture
- Share (Web Share where available, clipboard otherwise - no third-party
  button, no tracking script), a GitHub link, and a real privacy page written
  from what the code actually stores rather than from a template.

Button hierarchy
- Everything was an outlined box of roughly equal weight, so a screen's one
  real action, a settings toggle and a filter chip looked alike. Three tiers
  now: primary (filled, one per screen), default (outlined), quiet (toggles
  and filters, bordered only when hovered or active).
