Fixes #6230.

Summary

Backports the upstream reth eth_getLogs blocking-pool fix to the releases/v1.5.2 line by moving the reth pin to base/reth#38, which cherry-picks:

• fix(rpc): stop cancelled blocking IO tasks paradigmxyz/reth#26776: stop cancelled blocking IO tasks
• fix(rpc): hold a blocking IO permit for eth_getLogs range scans paradigmxyz/reth#26999: hold a blocking IO permit for eth_getLogs range scans
• perf(rpc): scan eth_getLogs ranges window by window paradigmxyz/reth#27000: scan eth_getLogs ranges window by window

main already has these through reth 2.7. Only Cargo.toml, Cargo.lock and etc/upstream-pins/reth.toml change: the reth source moves from tag = "base-v2.5.2.8" to tag = "base-v2.5.2.10" (e8ec60bd2fb001b93222daa47bc384d44932ef39, the base/reth#38 merge). The tag also carries base/reth#27 from base-v2.5.2.9 (full-preset RocksDB index downloads).

Testing

• fix(rpc): backport eth_getLogs blocking-pool fixes to v2.5.2 reth#38: cargo test -p reth-rpc --lib eth::filter (12 passed) and clippy -D warnings on reth-rpc and reth-rpc-eth-api.
• CI on this PR.
• Local devnet follower test: the affected releases reproduce the issue, and the patched build does not.
