update checkpoints

Two critical vulnerabilities allowed an attacker to flood the DragonX chain
with minimum-difficulty blocks starting at height 2879907:

1. ContextualCheckBlockHeader only validated nBits for HUSH3 mainnet
   (gated behind `if (ishush3)`), never for HAC/smart chains. An attacker
   could submit blocks claiming any difficulty and the node accepted them.
   Add nBits validation for all non-HUSH3 smart chains, gated above
   daaForkHeight (default 450000) to maintain consensus with early chain
   history that was mined by a different binary.

2. The rebrand commit (85c8d7f7d) commented out the `return false` block
   in CheckProofOfWork that rejects blocks whose hash does not meet the
   claimed target. This made PoW validation a no-op — any hash passed.
   Restore the rejection block and add RANDOMX_VALIDATION height-gated
   logic so blocks after the activation height are always validated even
   during initial block loading.

Vulnerability #1 was inherited from the upstream hush3 codebase.
Vulnerability #2 was introduced by the DragonX rebrand.
