Update app icons, fix sidebar path overflow, and remove terminal URL accumulator

Replace placeholder icons with the Triple-C branded logo at all required
Tauri sizes. Remove the host_path display from sidebar folder listings to
prevent text overflow. Remove the URL accumulator that injected clickable
login URL text into the terminal — the native WebLinksAddon still handles
URLs when the window is wide enough. Add explicit logging on container
removal confirming named volumes are preserved.
