When checkpoint verifier inserts canonical chain after rewind, the fork choice logic in writeBlockAndSetHead() may determine that no reorg is needed, causing blocks to be inserted with SideStatTy instead of CanonStatTy. This prevents writeHeadBlock() from being called, leaving canonical hash mappings outdated.

The issue manifests as:

• "Successfully inserted canonical chain" log appears
• GetBlockByNumber() still returns old block hash
• Fork detection triggers false positives for whitelisted blocks
• Milestone reorg protection fails

Fix by explicitly calling SetCanonical() after InsertChain() to force canonical status and ensure proper canonical hash mapping updates.
