fix: use compatible type import syntax

[copystring]

Summary

• Split the inline named type import in src/main.ts into a normal value import plus a separate import type.
• Keeps esbuild-register used by ioBroker integration tests from failing on the inline type import syntax.

Validation

• npm run test:integration
• npx eslint src/main.ts --max-warnings 0
• npm run typecheck
• git diff --check
