test(eigenda): trace DA host timeout

[fakedev9999]

What

• Enable Kona hint tracing in the EigenDA witness integration test.
• Fail witness generation after 180 seconds so CI preserves a focused error instead of hitting the one-hour job timeout.

Why

Identify the fine-grained preimage hint behind the repeated JSON-RPC -32602 response on main commit 13716c2.

Validation

• cargo fmt --all -- --check
• cargo test -p op-succinct-eigenda-host-utils --features integration --release --no-run

Notes

Temporary RCA instrumentation; do not merge.

RCA result (temporary diagnostics only):

• Reproduced on L2 blocks 8497795 -> 8497796.
• The failing hint is l2-block-header 0x01ec1aa2801be61f3e62032e6990cdffe6ca0df3e63ea5e736d85ce8a9da2113.
• Kona maps that hint to debug_getRawHeader(hash). The RPC returns -32602 Invalid params: number too large to fit in target type and Kona retries without backoff or a terminal error.
• The test timeout cancels host.run, but its spawned server task is detached on cancellation, so the process still does not exit; I force-cancelled the diagnostic run after preserving logs.

This PR remains a do-not-merge diagnostic.

Exact CI-secret probe result:

• eth_getBlockByNumber(8497788): succeeds, hash 0x01ec1aa2…9da2113.
• eth_getBlockByHash(0x01ec1aa2…9da2113): succeeds and returns block 8497788.
• debug_getRawHeader(8497788): succeeds, 629 bytes, keccak 0x01ec1aa2…9da2113.
• debug_getRawHeader(0x01ec1aa2…9da2113): fails with -32602 Invalid params: number too large to fit in target type at line 1 column 67.

Conclusion: this L2 RPC backend parses debug_getRawHeader input as a block-number quantity rather than accepting Kona’s hash parameter. It tries to deserialize the 256-bit hash into its numeric target type and overflows. Kona then retries that deterministic incompatibility forever. Temporary diagnostic; do not merge.
