Fix all non-existent database column references across codebase

- TrainerShow: period_start→date, total_amount→amount, status 'pending'→'active'
- trainer-show.blade: period_start→date, sessions_count→quantity, total_amount→amount
- AttendanceResource: actual_check_in→check_in_at, date→session.session_date
- InvoiceResource: invoice_number→number, balance_due→due_amount, remove description_ar
- ReportService: paid_amount→status check, cancellation_reason→withdrawal_reason,
  wallet status→is_active, remove frozen_amount
- SendDailySummary: Organization→Academy, is_active→status='active'
- SendParentWeeklyReport: fix morph type + join through session_date
- DeactivateExpiredEnrollments: expiry_date→end_date
- CertificateController + NotifyGuardianOfAbsence + RemoveAttendanceRecords:
  morph type 'participant'→Participant::class
- SendInvoiceCancelledNotification: cancellation_reason→notes
- DeleteParticipant: remove phantom refunded_amount reference
