feat(bar-app): legible tier chips, honest Icon label, dashboard auto-start

Lift chip text toward white so small tier badges (max/pro) read clearly on the
dark surface. Rename the icon toggle from Color/Mono to 'Icon' (it only swaps
the menu-bar icon, not the bar theme) to remove the misunderstanding. Make the
Dashboard button actually work when the server is down: probe reachability and,
if not up, launch 'ccs config' (detached) which boots the web-server and opens
the dashboard itself; degrade gracefully when the ccs binary isn't found.
