fix(channel): grid, scoreboard thumb, sort hash, visitor privacy

Audit fixes against /channel/{slug}:

1. Fluid video grid — repeat(auto-fill, minmax(260px, 1fr)) replaces
   the three fixed breakpoints (3/2/4 cols at 1101/1500/… px) that
   produced different card widths and could overflow 390 / 1280 /
   1920. min-width:0 on every grid child so a long unbroken title
   (CJK, "SPARTAWORRIOR") can't widen its track past 1fr.
2. Scoreboard thumbnail — stop including vs-mini + scorebar-mini on
   match cards. Those partials leaked fighter names, "AKA/AO",
   "ROUND 1", "0:00" into the card DOM, showing stale 0-0 for
   finished matches and breaking title layout at narrow widths. The
   regular <img> above is the thumbnail now; VS intro + live scorebar
   still render on the full match player page where they belong.
3. Sort pills — Latest/Popular/Oldest now append #videos so the page
   stays on the Videos tab after reload instead of jumping to Wall.
4. Shorts tab — always render for the owner (so the "My Shorts"
   sidebar link always lands somewhere), with an empty-state card
   when no shorts exist. Visitors still see it only when shorts > 0.
5. Subscriptions sidebar link — href="#" replaced by a real
   /feed/subscriptions route backed by UserController@subscriptionsFeed
   that reuses the videos/index view with the subscription feed.
6. Header view count — totalViews now sums video_views over public
   videos for visitors (owner still sees the full total). Previously
   leaked unlisted and private video view counts.
7. Card redundancy — new hideChannelInfo prop on <x-video-card/>
   suppresses the per-card avatar + channel-name row. The channel
   page passes it; everywhere else keeps the row.
9. Decorative logo — the second <img alt="Play"> in the responsive
   header pair now has alt="" so a screen reader doesn't announce
   "Play Play". ⋮ menu button gets aria-label="More actions".
10. Privacy — age, gender, location and horoscope strip now only
    render to the owner on the channel header (horoscope strip is
    also allowed when the compatibility match-up is being shown to
    a signed-in visitor). Joined-month stays public.
11. Notifications dropdown — initial state is "No notifications"
    not an indefinite "Loading…". Opening the panel now shows a
    spinner while fetching, surfaces a Retry button on error, and
    bails out of the "Loading…" state on non-ok HTTP responses.

Title clamp — .yt-video-title is now a 2-line box with
overflow-wrap:anywhere so CJK titles and long words wrap mid-word
and can't widen the card past its track.
