- Change all permission codes from colon (`:`) to dot (`.`) separator
to match handler require_permission() calls consistently
- Add missing user.list, role.list, permission.list, organization.list,
department.list, position.list permissions (handlers check for .list
but seeds only had :read)
- Add missing message module permissions (message.list, message.send,
message.template.list, message.template.create)
- Add missing setting.delete, numbering.delete permissions
- Fix workflow handlers: workflow: → workflow.
- Fix message handlers: message: → message.
- Update viewer role READ_PERM_INDICES for new permission list
This fixes a critical runtime bug where ALL permission checks in
erp-auth and erp-config handlers would return 403 Forbidden because
the seed data used colon separators but handlers checked for dots.
