chore(match-css): remove two blocks of dead cascade-overridden CSS

Two provably-unreachable blocks in resources/views/videos/types/match.blade.php
whose cascade targets are overridden further down with !important:

1. The pre-override pair at ~line 320:
     .events-sidebar { display: none; }
     .events-sidebar.show { display: flex; }
   is overridden by the primary .events-sidebar definition further down
   that sets `display: none !important` and `.show { display: flex !important }`.

2. The first `@media (max-width: 1300px)` block that sized
   .yt-sidebar-container + .events-sidebar to 300 px is overridden by the
   SECOND `@media (max-width: 1300px)` block immediately after, which sets
   both to `width: 100% !important` as part of the stacking layout. Same
   breakpoint, same selectors, !important wins.

Both removals leave Blade comments in place so the next reader can see why
the gap is there. Smoke-tested: /, /videos still 200; full test suite
80/80 green. Full consolidation of the four responsive .events-sidebar
variants (desktop, 1300 px stacking, 991 px bottom sheet, fullscreen
drawer) is left for a future turn with a browser visual-regression
harness — each variant has a distinct behavior that would be risky to
merge without one.
