Afonso Coutinho 10e797a1aa Normalize scheduled email offsets before storage
Normalize scheduled email send_at values with timezone offsets or Z suffixes to naive UTC before storing, matching the poller's lexicographic comparison format and preventing early/late sends.

"""Scheduled emails with a TZ offset or Z suffix must fire on time.
POST /api/email/schedule validated send_at by parsing it (handling Z and
offsets) but stored the RAW client string. The poller selects due rows
with a lexicographic string compare against a naive UTC isoformat, so a
"17:01:00+02:00" schedule (15:01 UTC) did not fire until 17:01 UTC (~2h
late) and a "13:00:00-05:00" schedule (18:00 UTC) fired at 13:00 UTC (5h
early).
