feat: redesign admin panel with glass morphism UI, animated background, and stats bar

- Rewrite AdminPanel with cosmic floating orbs background using theme colors
- Add stats bar: uptime, bot version, cabinet version, trial/paid counts from API
- Glass morphism cards with 3D tilt effect (rAF-throttled) and entry animations
- Live search with Cmd+K shortcut, highlight matches, permission-aware filtering
- Register Tailwind `light:` variant for proper light theme support
- Mobile optimizations: reduced orbs (3), lower blur (80px), compact 2-col stats
- Telegram MiniApp safe area support via useTelegramSDK
- Full accessibility: aria-hidden on decorative SVGs, aria-labels, role="status"
- React.memo on StatsBar, GlassCard, CosmosBackground for render performance
- Memo-stable section refs via Set<id> pattern to preserve GlassCard memo during search
- i18n keys added to all 4 locales (ru, en, zh, fa)
