Fix frozen video feed on window reopen and add construct SFX

- Use `video.resume()` instead of `video.play()` in Build, Map, Quest,
  and Research windows: Phaser v4's `play()` is a no-op after `pause()`
  because the `_playCalled` flag stays true, leaving the feed frozen
  after close → reopen. `resume()` handles both first open and re-open.
- Play the 'construct' SFX when the planet HUD lines start their
  scramble-decode animation in SurfaceScene.
