Initial commit: TravelHub multi-tenant flight booking platform

Angular + Go + PostgreSQL sample with strict per-tenant isolation.

- Backend: Go API (basic auth, tenant-scoped repository layer, pgx pool)
- Frontend: Angular 22 SPA (search, checkout, bookings, dashboard)
- Database: schema, seed data and demo bookings migrations
- Tests: 311 across Go (integration), Angular (unit) and Playwright (e2e),
  plus a generated evidence report with PDF export
- Security: whitebox VAPT report under security/

Secrets (.env, tokens, DB credentials) are git-ignored.
