Let students cancel their own lessons from the booking page
Adds POST /bookings/{id}/cancel (owner-only, idempotent): marks the lesson
cancelled, releases the availability slot for rebooking, and voids a
still-pending payment so it leaves the admin confirmation queue. Paid
payments are untouched — refunds stay a manual admin decision.

The instructor PATCH /bookings/{id}/status path now does the same slot
release and payment voiding on cancellation (previously cancelled lessons
left their slot permanently booked), and reinstating a cancelled lesson
re-claims the slot, rejecting with 409 if the freed time was rebooked.

The "Your upcoming lessons" panel gets a Cancel button with a confirm
prompt; on success both the lesson list and the slot calendar refresh.
