[codex] remove sei debug trace exclude endpoints

[codchen]

Summary

Removes the legacy sei_traceBlockByNumberExcludeTraceFail and sei_traceBlockByHashExcludeTraceFail RPC endpoints.

Because those were the only methods on SeiDebugAPI, this also removes the SeiDebugAPI wrapper and its sei namespace debug registration. The related legacy allowlist entries, config examples, RPC IO fixtures, docs, and endpoint-specific tests were removed as well.

Impact

Clients should use the standard debug_traceBlockByNumber and debug_traceBlockByHash endpoints for block tracing. The remaining legacy *ExcludeTraceFail block and receipt APIs are unchanged.

Validation

• go test ./evmrpc ./evmrpc/tests

PR Summary

Medium Risk
Breaking RPC removal for any client still calling the two sei_trace*ExcludeTraceFail methods; scope is limited to deprecated legacy trace APIs with a documented debug_* replacement.

Overview
Removes the legacy sei_traceBlockByNumberExcludeTraceFail and sei_traceBlockByHashExcludeTraceFail JSON-RPC methods, including the trace-cache filtering path (dropUntraceableTraces, filterExcludeFailFromBlockCache) that only served those calls.

Because those methods were the sole handlers on SeiDebugAPI, the PR drops that wrapper and stops registering a sei-namespace debug service on the HTTP EVM server; debug_traceBlockByNumber / debug_traceBlockByHash are unchanged.

Also cleans up allowlist entries in enabled_legacy_sei_apis (docker configs, evmrpc/sei_legacy.go, config template), docs (evmrpc/README.md), integration RPC IO fixtures/README rows, and Hardhat/Go tests tied to the removed APIs. Comments on isPanicOrSyntheticTx / isReceiptUntraceable now note they still support the remaining sei_get*ExcludeTraceFail block and receipt endpoints.

Client impact: callers on the removed trace methods must switch to standard debug_* block tracing; other *ExcludeTraceFail sei_* APIs are untouched.
