fix(db): писать null в пустые FK и мигрировать старые БД без apiType

Пустая строка в vpsId/providerAccountId/providerId давала 500
SQLITE_CONSTRAINT_FOREIGNKEY при создании платежа, записи баланса и VPS
без провайдера. Старые БД падали с «no such column apiType»: добавлены
колонки providers.apiType/apiBaseUrl и перенос URL BILLmanager с аккаунтов.
