test(config): chat defaults for uploads come from measurement, not a guess (red)

Browse Source 
iguana/gemma4-26b answered correctly at 90,000 chars but SILENTLY dropped the
head of a 120,000-char transcript (prompt tokens fell to 16k; 'not in the
text'); koala/phi4-mini has an 8,192-token context and answers HTTP 400 at
~13k tokens. So the budget is 90,000 and the upload chat model defaults to
gemma4-26b. Red: UploadChatModel is undefined.
