feat(leads): 2-hour admin review window before leads appear in supplier feed

New visible_from column on lead_requests set to NOW + 2h on both the
direct insert (logged-in user) and the email verification update.

Supplier feed, notify_matching_suppliers, and send_weekly_lead_digest
all filter on visible_from <= datetime('now'), so no lead surfaces to
suppliers before the window expires.

Migration 0023 adds the column and backfills existing verified leads
with created_at so they remain immediately visible.
