Issue #19 — Backend: Email Notification — Booking Cancelled

[yusuftomilola]

Location:

• backend/src/bookings/providers/cancel-booking.provider.ts
• backend/src/email/email.service.ts
• backend/src/email/templates/booking-cancelled.hbs

Description

When a booking is cancelled — whether by the member themselves or by an admin — the member should receive an email notifying them of the cancellation. The email should indicate who initiated the cancellation so the member has full context.

Acceptance Criteria

• A Handlebars template is created at backend/src/email/templates/booking-cancelled.hbs displaying:
  • Member's full name
  • Booking ID
  • Workspace name
  • Original start date and end date
  • Who cancelled the booking ("you" if self-cancelled, "an administrator" if cancelled by admin)
• A sendBookingCancelledEmail(to: string, fullName: string, data: {...}) method is added to EmailService
• EmailService is injected into the cancel booking provider
• After the booking status is saved as CANCELLED, the email is fired with .catch(() => void 0)
• The cancel booking provider determines the cancelledBy value by comparing the requesting user's ID and role to the booking owner
• npx tsc --noEmit passes with no errors
