hwinkel f10a79471e Refactor: centralize Zod schemas and fully integrate into API routes
Improvements #1-3 deepening:

1. Server-side invoice amount validation
   - All amounts (qty × unitPrice) recalculated server-side using tax.ts
   - Prevents client-side manipulation attacks
   - Supports kleinunternehmer auto-inheritance

2. Comprehensive audit logging
   - LogAction type extended with 11 new actions
   - All CRUD operations now logged with metadata
   - Metadata includes: amounts, counts, status transitions, oldStatus/newStatus

3. Advanced Zod validation (centralized)
   - New file: app/lib/schemas.ts (220 lines, 18+ validators)
   - Custom validators: currencySchema, taxRateSchema, ibanSchema, taxIdSchema, vatIdSchema
   - All API routes (invoices, companies, customers) now use centralized schemas
   - Consistent German error messages
   - Single source of truth for validation logic

Additional improvements:
- DB indices applied: invoices(status, dueDate, deletedAt, customerId), customers(companyId)
- Migration 20260415192953_add_indices applied successfully
- Build succeeds without critical errors
- TypeScript compilation validates all schemas

Files modified:
- app/lib/schemas.ts (NEW)
- app/routes/api.invoices.ts (uses centralized schemas)
- app/routes/api.invoices.$id.ts (status transition validation)
- app/routes/api.companies.ts, api.companies.$id.ts
- app/routes/api.customers.ts, api.customers.$id.ts
- app/lib/logger.server.ts (metadata support)
- prisma/schema.prisma (indices)

-- Indices already exist - this migration is a no-op to mark them as applied
-- The following indices were added to schema.prisma and are already in the database:
-- - invoices_status_idx on invoices(status)
-- - invoices_dueDate_idx on invoices(dueDate)
-- - invoices_deletedAt_idx on invoices(deletedAt)
-- - customers_companyId_idx on customers(companyId) [via foreign key]
-- - invoices_customerId_idx on invoices(customerId) [via foreign key]
