fix(tui): paint ! caveat lines amber instead of bold red

The "! " notes -- the unpriced/$-estimate hint that trails nearly every
overview on subscription sources, the unknown-model note, the $0.00
explainer -- all shouted in bold red, the color of errors. They now use
the amber warn tier (matching the toast palette); red is reserved for
the error toast and the B-scale token heat cue. The five duplicated
prefix-styling blocks collapse into one line_attr helper, which also
gives every pane the dim "· " caption style.
