Fix leo test network execution

[DicksonWu654]

Summary

• Dispatch compiler test execution through the selected Aleo network instead of hardcoded Testnet types.
• Keep the existing testnet runner APIs compatible while adding network-aware runners for CLI tests.
• Adapt the deterministic development genesis data for mainnet and canary ledger runs.

Tests

• cargo check -p leo-compiler
• cargo test -p leo-compiler run::tests::evaluation_runner_uses_selected_network --lib -- --exact --nocapture
• cargo test -p leo-compiler test_execution::execution_tests::execution_metadata_leo --lib -- --exact --nocapture

The full leo-lang check is unavailable in this environment because librocksdb-sys cannot find libclang. The workspace-wide stable cargo fmt check also reports existing formatting differences from unstable rustfmt settings; the edited files were formatted and checked with nightly rustfmt.
