fix(gateway): name what the /status token number actually is

Sharpen the label from 'Session usage (cumulative)' to 'Cumulative API
tokens (re-sent each call)'. The number is real provider-reported usage
summed across every API call in the session — not context size. In an
agentic loop the same context is re-sent each iteration, so a one-hour
tool-heavy session legitimately reaches tens of millions of tokens. The
new label explains the magnitude so users stop reading it as a bug or as
a total across all sessions.
