Scale demo seed data down for tutorial recordings

Customers: 100 → 27 (15 commercial across auto/industrial/architectural/
fitness/marine/energy, including 2 tax-exempt govts; 12 individuals)

Quotes: 75 → 20; date range extended to 4-6 months (was 90 days);
status distribution adjusted proportionally (2 draft, 3 sent, 10 approved,
3 rejected, 2 expired)

Jobs: fixed 50-loop → per-customer 0-5 jobs (~32 total); jobIdx cycles
all 16 statuses globally so every status is visible; creation dates spread
across 1-5 months for in-progress/early jobs, 2-6 months for completed jobs

SeededCustomerEmails updated to match new 27-customer set (added
gnelson@email.com and carol.evans@email.com)
