feat: add client disable/deletion with soft-delete (#67)

Add soft-delete support for clients: disable is the default action
(hiding from client list and booking flow), with permanent deletion
requiring explicit type-to-confirm. Disabled clients remain in
reporting and can be re-enabled by staff.

- Add client_status enum (active/disabled) and disabled_at column
- API defaults GET /api/clients to active-only, ?includeDisabled=true shows all
- PATCH /api/clients/:id accepts status field for disable/enable
- DELETE requires ?confirm=true query param
- Booking flow skips disabled clients
- Frontend: show disabled toggle, disable/enable buttons, delete confirmation modal
