fix: avoid deadlock in commit_artifacts and stabilize golden_execute test

[jverdicc]

Motivation

• Fix a deadlock observed in commit_artifacts when ASPEC rejects a wasm module while the state.claims lock is still held, which caused golden_execute_claim_capsule_hash_and_etl_index_stable to hang indefinitely.
• Ensure the test fails fast and gives a clear diagnostic if a future deadlock or infinite await occurs.

Description

• Change commit_artifacts (crates/evidenceos-daemon/src/server/handlers_v2.rs) to record ASPEC rejection under the claims lock, set a local aspec_rejected flag, drop the lock, call persist_all_with_trial_router, and only then return the FailedPrecondition error if the module was rejected (avoids persisting while holding claims).
• Update the golden test (crates/evidenceos-daemon/src/server/core.rs) to assert the deterministic ASPEC rejection behavior for the burn wasm module and wrap the test body in tokio::time::timeout(Duration::from_secs(10), ...) so hangs fail fast with a clear message.
• Small formatting / bookkeeping adjustments to keep the modified flow clear and maintain state persistence semantics.

Testing

• Ran cargo fmt --check, which succeeded.
• Ran the targeted test cargo test -p evidenceos-daemon --lib server::tests::golden_execute_claim_capsule_hash_and_etl_index_stable -- --nocapture, which passed after the fix.
• Attempted a full workspace test run (cargo test --workspace), but the full workspace run was not completed here due to long compile/test runtime in this environment.
