Subject: [PATCH] fix: route resume grading through AI Gateway to stop false
 'future dates' flag (SIL-3430)

The google() direct serving of gemini-2.5-flash intermittently flags past
'Present' start dates as being in the future, dragging excellent resumes down
to grade C. The same model via the Vercel AI Gateway does not reproduce this
(0 hallucinations across an isolated same-code A/B). Route grading through the
gateway. Requires a paid AI_GATEWAY_API_KEY in prod.
