Add chain_id field to all block import test requests

- Add chain_id parameter to importBlock requests in all verification tests
- Update test_block_import.py to use high block heights to avoid conflicts with existing chain
- Simplify test_block_import.py to focus on core validation (hash, parent, conflict)
- Fix test_block_import_complete.py to use head block instead of block 1 for existing block test
- Update expected response format from status field to success field
