Performance optimizations, a11y gaps, NETOWRK_PLUGIN typo, and architecture improvements

[Copilot]

Nine medium-priority findings addressed: Zone.js over-patching, a misspelled injection token, eager preloading of all routes, inconsistent platform detection, overly broad CUSTOM_ELEMENTS_SCHEMA, duplicate API-triggering observables, missing ARIA on camera UI, constructor-based subscriptions, and unguarded subscriptions in settings.

Changes

Performance

• Zone.js: Add __zone_symbol__UNPATCHED_EVENTS to zone-flags.ts — scroll, mousemove, touchmove, pointermove, mouseenter, mouseleave, resize no longer trigger change detection
• Preloading: Replace PreloadAllModules with SelectivePreloadingStrategy; only routes marked data: { preload: true } (login, home) are eagerly fetched
• Duplicate API calls: Add hasNewInbox$ to DiaBackendTransactionRepository with shareReplay({ bufferSize: 1, refCount: true }); both HomePage and CaptureTabComponent subscribe to the shared stream instead of each independently driving inbox$

Bug / Naming

• Typo: NETOWRK_PLUGIN → NETWORK_PLUGIN across capacitor-plugins.module.ts, capacitor-plugins-testing.module.ts, network.service.ts

Architecture

• Platform detection: Replace Capacitor.getPlatform() == 'android' / !== 'android' with Platform.is('android') from @ionic/angular in media.component.ts and dia-backend-notification.service.ts
• CUSTOM_ELEMENTS_SCHEMA: Remove from SharedModule — it was silencing ALL unknown-element errors app-wide; leaf modules that actually use Swiper web components (details, go-pro, tutorial) already carry the schema
• Constructor subscriptions: Move active subscriptions in HomePage and CaptureTabComponent constructors into ngOnInit() to avoid premature side-effects and improve testability
• Unguarded subscriptions: Add untilDestroyed(this) to emailVerification() and copyPrivateKeyToClipboard() in SettingsPage — both were escaping @UntilDestroy({ checkProperties: true }) because they are not assigned to class properties

Accessibility

• Add role="button", tabindex="0", aria-label, aria-pressed, and keyboard handlers (keydown.enter, keydown.space with $event.preventDefault()) to all interactive <div> and <mat-icon> elements in custom-camera.page.html

// Before — each component independently subscribed to inbox$, causing 2 API call chains
readonly hasNewInbox$ = this.diaBackendTransactionRepository.inbox$.pipe(
  map(transactions => transactions.count !== 0),
  startWith(false)
);

// After — single shared stream in the repository
// DiaBackendTransactionRepository
readonly hasNewInbox$ = this.inbox$.pipe(
  map(transactions => transactions.count !== 0),
  startWith(false),
  shareReplay({ bufferSize: 1, refCount: true })
);

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Closing this stale Copilot draft PR. It is outdated against main, not merge-ready, and bundles broad automated changes without current full CI coverage. We should re-open focused PRs only for findings that are still valid after current main/Angular 21.
