Fix source maps + reader UI redesign

- Strip v prefix from GlitchTip release name in upload-sourcemaps job
  so it matches PUBLIC_BUILD_VERSION reported by the deployed app
- Focus mode: hide bottom nav/comments, show floating prev/next/exit pill
- Listening mode: full-screen overlay with transport, speed pills, voice selector
- Settings panel: dedup speed/auto-next/sleep controls (single source of truth)
- Mini-bar: unified speed steps, headphones button opens ListeningMode
