feat: Recurring invoices + license suspend on dunning level 3 (PRD §6.4/§6.6)

- Recurring API: list contracts needing invoicing + run endpoint - Auto-generate draft invoices for Wartung/SLA + Dienstvertrag contracts - Automatic license suspension at dunning level 3 (PRD §6.4) - Recurring billable expenses tracking - MRR/ARR computation from contracts + expenses - Prisma: added Contract.company + Expense.company relations - Scheduler info (pg-boss monthly cron in production)
