resume playback from current position, force light theme, fix speed button label

- Play/pause toggle now resumes from current timeline position instead of restarting
- Force white background on all devices regardless of dark mode preference
- Speed button shows 0.5x by default so users know half-speed is available
- Add ben.mp4 and andy.mp4 recording to database
