Fix iOS streaming input bugs and expand Liquid Glass UI

[Kief5555]

This PR fixes several streaming input issues and extends the Liquid Glass aesthetic throughout the iOS app.

Streaming Fixes (StreamerView.swift, OpenNOWStore.swift):

• Fix sub-pixel mouse movement loss by accumulating fractional deltas with accDX/accDY and using Math.trunc().
• Ensure native keyboard raises by calling kbInput.focus() synchronously in showKeyboard().
• Fix ws.onclose to properly close RTCPeerConnection and add auto-reconnect logic with reconnectTimer.
• Respect preferredQuality in streamProfile (Data Saver: 720p/15Mbps, Quality: 1440p/50Mbps).
• Restart session tasks in OpenNOWStore.dismissStreamer() to enable auto-representation of the streamer.

Liquid Glass UI Expansion:

• Add ultra-thin material navigation bars to HomeView, BrowseView, SettingsView, SessionView, and LibraryView.
• Add ultra-thin material tab bar background in ContentView.
• Apply brand-tinted gradient to appBackground in ContentView.
• Update FilterChip in BrowseView to use glass effect on iOS 26+.
• Apply glass list row backgrounds to all SettingsView rows.
• Update endSessionButton in SessionView to use glass effect styling.
• Update HUD overlay in StreamerView to use glass styling.
• Tweak GlassCardModifier shadow in HomeView.
