player: extract branded .pjs player into shared static/player.{js,css}
One source of truth for the branded player on desktop (archive) and
mobile. The ArchivePlayer class moves out of app.js into player.js
(name kept; app.js still does `new ArchivePlayer`); the .pjs styles
move out of style.css into player.css. Both archive.html and mobile.html
load the shared module before their own script.
The shared player gains two additive, backward-compatible options:
- live: timeline hidden, only pause/play + fullscreen (mobile Live).
- autohide:false: control bar always visible (touch); desktop keeps
autohide (default true), so desktop archive behaves exactly as before.
Fullscreen is now self-contained (no global toggleFullscreen dep) so it
works on mobile too, with an iOS <video> fallback.
mobile.js drops its duplicated Player class and uses ArchivePlayer.
Verified on .79: /archive 200 loads player.{js,css}; app.js has no
class def; mobile (Host :8443) loads the shared module.

// Режимы:
|

// transcode — серверный H.264-поток без Range: виртуальный таймлайн на duration,

// file — нативно перематываемый файл (HW-декод H.265): v.currentTime/duration.
|

// live — без таймлайна: только пауза/плей + fullscreen (src без длительности).
|
||||
// opts: { mode, live, duration, srcFor(startSec)->url, src, offset, onEnded, onTime, spIdx, autohide }
