Fix all TypeScript errors: restore proper types and typed route casts

- Restore `as any` casts for Next.js typedRoutes on dynamic routes
- Use proper types for PDF templates, invoice/expense data, DB schema
- Fix PgColumn casts in sort helpers for expenses/invoices
- Add null guards for optional port/client in record-export
- Fix vitest config (remove invalid poolOptions)
- Lint: 0 errors, TypeScript: 0 errors
