feat: ANSI color rendering in preview snapshots

Server: add -e flag to tmux capture-pane to preserve escape sequences. Frontend: ansiToHtml() parser converts SGR codes (bold, italic, dim, 16-color, 256-color) to <span> tags with inline styles. Applied to dashboard tiles, sidebar items, and hover overlay. No external deps.
