test(support): add deleteUserPfx helper to remove user certificate

Add deleteUserPfx() to playwright/support/nc-provisioning.ts to send
DELETE /ocs/v2.php/apps/libresign/api/v1/account/pfx authenticated
as the target user. This ensures tests that require the certificate
creation flow always start from a clean state.
