4grayandClaude Opus 4.7 bbbe7b4036 perf(renderer): inline splash + sync language hint + drop legacy polyfill
Three first-paint fixes for cold app start.

#1 — Inline splash in index.html
Cold start used to show a blank Material-grey background until the
~1.5MB preloaded chunk + 300KB styles.css downloaded and Angular
bootstrapped. On slow disks/networks that's 1-3+ s of "is the app
frozen?" before any pixel of UI appears.

Add a self-contained splash (inline CSS, no extra HTTP, no assets) —
"IPTVnator" wordmark + a CSS spinner — that paints immediately from
the parsed HTML. Removed in main.ts after bootstrapApplication()
resolves, gated on requestAnimationFrame so the swap happens after
AppComponent's first paint (no flash of empty background between
splash removal and the real UI).

Respects prefers-reduced-motion (spinner stops, opacity dims).

#3 — Drop legacy `global = window` polyfill
The inline <script> in <head> ("if (global === undefined) var global =
window") was a workaround for an older library expecting Node's
`global`. Verified nothing in the current bundle reads window.global
(the only matches are TypeScript `declare global { ... }` blocks and
unrelated route paths). Removes one render-blocking inline <script>
parse from the critical path.

#5 — Synchronous language hint
Settings live in IndexedDB (via @ngx-pwa/local-storage), which the
TranslateModule cannot read synchronously at bootstrap. So the first
render historically used English regardless of the user's preference,
then re-rendered every TranslatePipe in the tree once initSettings()
finished — visible flash for non-English users.

Mirror the active language to localStorage in initSettings() once the
IDB-backed settings resolve. Add getInitialLanguage() in app.config.ts
that reads that key synchronously before bootstrap and passes it to
TranslateModule.forRoot({ defaultLanguage }). First-ever boot still
falls back to English (no hint yet); every subsequent boot renders in
the saved language from the very first frame.
