The gateway now records every call's token counts (read from the provider's
own usage block, in both the translated and the pass-through paths) with the
calling agent taken from the client's User-Agent, into
~/.config/dial/usage.jsonl. A Usage tab sums them by period, agent and
model, with a per-hour/day/week timeline and cost at models.dev list
prices; dial usage does the same in the terminal.
Also nudges the window header 1pt up so the brand sits level with the
traffic lights, and lets ?view= open the window on a tab.
