Add Invoice Correction Wizard for superadmins

4-step wizard: search participant → select invoice → enter correction
(new amount, description, reason) → creates remainder invoice if needed.
Full audit log trace via Log::channel('audit') and invoice metadata.
Accessible from SuperAdmin panel, gated by super_admin.access permission.
