VS intro screen (arena design), card VS mini + live scorebar, full country names, sports-match edit fix

Match player + preview
- Rebuild VS intro as a 1920×1080 scaled canvas (arena design from drafts/):
  angled RED/BLUE panels with clip-paths, slam-in VS with pulse+shine,
  event/stage/weight header, Match/Court/Referee chips, per-fighter
  Record/Rank/Stats chip row. Every placeholder from the artifact is
  always in the DOM; empty ones are hidden by `.vs-nullable:empty`
  and `.vs-nullable-hide` so the layout adapts without losing the
  design's HTML shape. Country codes always render as full country
  names (via new App\Data\Countries::name()).
- Real-time 6s countdown Skip button; video pinned at t=0 while
  the intro runs, released to play at zero or on Skip.
- Standalone preview page at /videos/{video}/vs-preview.

Video cards (home + everywhere)
- Match cards get a `vs-mini` overlay of the same arena design
  (fixed canvas, per-card ResizeObserver, animations replay every
  time the mouse leaves the thumb). On hover the mini explodes
  outward (panels fly out, VS scales+blurs+fades) and the hover
  video plays over the cleared thumb.
- Match cards also render a `scorebar-mini` overlay (verbatim of
  the full-player msb-scale scorebar + msb-feed) that shows
  during hover playback. Live-scoring is wired per-card via a
  data-sbm-state payload of rounds+points; RED/BLUE score, round
  label, per-round clock, and the top-right Live Scoring ticker
  (4 entries, sport-aware Yuko/Waza-ari/Ippon or Punch/Body
  kick/… labels) all update from the mini video's timeupdate.

Bug fixes
- Hover video wasn't playing sound: dropped the `muted` attribute
  I'd added while debugging match previews.
- White flash strobing on the left of match cards: removed the
  `.vs-mini-flash` element (intro-only flourish that fired on
  every mouseleave replay).
- Sports-match modal was showing "Please complete the required
  fields" when saving basic info for match videos that had no
  SportsMatch row yet: the submit gate only checked matchId, not
  the attached videoId; now it correctly skips uploadVideoFirst()
  in both edit and attach-existing-video modes.

Country names project-wide
- New helper App\Data\Countries::name($iso2) → full country name.
- Swapped `?? country` fallbacks to `?? Countries::name(country)`
  in admin dashboard, video-analytics, video-insights payloads
  (VideoController + SuperAdminController), and the VS partials.
  Now user-visible country labels always show "Bahrain" instead
  of "BH", including chart tooltips and modal titles.
