gnd: add file data source tests and split fixture subgraphs

Add IPFS and Arweave file data source test fixtures and split the
monolithic gnd_test fixture into four focused subgraphs:

- token/            ERC20 events, eth_call mocking, dynamic templates
- blocks/           Block handlers (every, once, polling filters)
- receipts/         Transaction receipts (receipt: true handlers)
- file-data-sources/ IPFS and Arweave file data sources

Each fixture is a standalone subgraph with its own schema, mappings,
ABIs, and test JSON files. The Rust test harness is updated to use a
generic setup_fixture(name) helper, with one test function per fixture.
