Subject: [PATCH 1/3] A voice command is refused before it is sent if it would
 pass the daily budget

The voice agent only checked whether the budget was already spent, so the
last command of the day went through in full and could end it over budget.
It now estimates the command from its request size, as contexts and AI Task
do, holds the estimate while the call runs, and reports the size to the
tracker so the estimate learns from voice requests too.

Subject: [PATCH 2/3] The voice refusal for the budget is true when tokens
 remain, and is an error

The check refuses a command whose estimate does not fit, which happens
with tokens left. The line said the budget "is spent". It now says not
enough is left, in all 13 languages.

With no fallback agent, the reply was an action_done response. The Assist
dialog and a satellite read that as a command that went through. It is
now an error, no_intent_match for a sentence not understood and
failed_to_handle for the budget, a rejected key and no answer, as the
default agent answers.
