feat(ui): mobile mesh tabs, AIUI-style audio player, cloud grid + map fixes

UI (this session):
- Global audio player now scales the whole interface into the space above it
  on desktop (sidebar + main) and docks directly above the tab bar on mobile;
  it stays visible while navigating.
- Mesh mobile redesign: floating Chat / BTC / Dead Man / AI / Map tab strip
  with a single fixed, internally-scrolling pane (page no longer scrolls);
  tabs hide while a conversation is open; floating back button; collapsible
  Device panel (starts collapsed); keyboard-aware conversation sizing via
  VisualViewport so the chat sits just above the keyboard.
- Cloud file grid: uniform 4/3 card heights (folders + images match).
- Swipe left/right switches tabs on the Apps and Web5 screens.
- Map tool fills its pane (no bottom gap); fix skewed Share Location toggle
  on mobile (global min-height rule was deforming the switch).
- Trim redundant helper copy from the mesh AI tab.

Also bundles pre-existing in-progress work that was already in the tree:
mesh listener/session + wallet + container + bitcoin-status backend changes,
docker UI updates, and assorted other UI tweaks.
