…nts (#22050) Improved logging based on audit finding 114 in #21500 + random improvements that I noticed could be done ## Summary - Adds warning logs in PXE block synchronizer when `getBlockHeader` returns null for `chain-proven` and `chain-finalized` events, instead of silently skipping the anchor update. - Aligns with the `chain-pruned` handler which already throws on missing headers. Closes #21500 .

Summary
Backport of #22050 to v4-next.
Cherry-pick applied cleanly. The noir-projects change from the original PR was already present on v4-next, so only the PXE block_synchronizer changes were needed.
