fix: rewrite UI as pure SwiftUI, fix crash/fullscreen/height issues

- Skip BricksView, render video directly in SwiftUI (fixes 1/3 height)
- Fullscreen uses plain NSView+AVPlayerLayer (fixes objc_release crash)
- Remove NSApp.hide(nil) (fixes fullscreen not showing)
- Add volume +/- buttons and volume slider indicator
- Add iOS/iPadOS support with #if os guards
- ProgressSlider decoupled from BricksEngine
- PlayerBridge no longer depends on player.ui JSON
