Subject: [PATCH] Fix OpenRouter FX lookups and the Vercel charges end date

OpenRouter's activity API dates each row as "2026-11-08 00:00:00". The
connector passed that through as the line date, so the sync asked
Frankfurter for /v1/2026-11-08 00:00:00, got a 404, and the connection
errored for any workspace not in USD. Lines now carry the day alone;
externalIds are unchanged, so stored lines are updated, not duplicated.

Vercel's billing charges request ended at midnight after today, a
moment in the future, and the connection failed with a 400. The end is
now capped at the start of the current UTC day; today's charges come
with the next sync, which rereads the last 3 days.
