Wahab can now enter historical tickets that keep their true reported date: - Add nullable tickets.reported_at (DateTime) via alembic d5e0f2a1c3b4; backfill existing rows from created_at so nothing shows empty. - TicketCreate.reported_at (optional) is persisted by create_ticket and defaults to now when omitted, so existing create behavior is unchanged. - New-issue form gains a 'Reported Date' date picker (defaults to today, past dates allowed, future blocked) and sends reported_at in the payload. - List and detail pages show 'Reported' next to 'Created' (date-only, labeled) so backdated tickets are obvious; SLA deadline is unchanged and still runs from creation time so backfilling never instantly breaches. - Tests: backdated create persists + is exposed on list/detail; omitted reported_at defaults to now; SLA window unchanged; full datetime round trip.
