Agent computer: terminal (tmux + drives + tabs), Obsidian vault, UI polish

Terminal app (xterm ⇄ WebSocket ⇄ per-agent themed container):
- zsh + oh-my-zsh + powerlevel10k image (agent-terminal), runs as uid 65532 to
  share read-write ownership of the file-drive volume with the server.
- Interactive PTY in cm-sandbox (bollard exec tty/attach + resize) + a
  TerminalManager; ticket-authed WS bridge routed straight to the backend via a
  Traefik PathRegexp(/ws) rule. MOTD greets the user by name.
- tmux resumable sessions; multi-tab (one tmux session per tab, same container),
  drag-to-reorder, rename, and a Save that persists named tabs to the server
  (terminal_tabs, migration 0014) so they survive logout / a new device.
- Files drives mounted per-agent (subpath) at ~/drives/{documents,received,
  shared}; a reconciler keeps the Files app's index in sync with terminal writes.
  Storage moved to a shared `filedata` volume (CLAWMATES_STORAGE__DATA_DIR).

Obsidian vault (a markdown "second brain" per agent):
- New `vault` FileDrive (migration 0015) mounted into the terminal at ~/obsidian;
  a file-content read route; a purple Obsidian tile + a vault viewer app.

Computer UI:
- Draggable computer-panel width (min = phone preset) keeping the size presets.
- Green Terminal glyph, "Claw Chat" → "Chat", colored gradient-outline app icons.
- Agent page: avatar↔activity-grid spacing + larger, uniform section fonts with
  colored section-tinted tag chips.
