fix(vm): relocate pqc precompile addresses to avoid conflicts

[Federico2014]

What does this PR do?

Relocates the five PQC precompile addresses from the 0x16–0x1a range to the 0x02000016–0x0200001a namespace to avoid collisions with future Ethereum-compatible precompiles occupying the lower address space. Updates all related comments and test files accordingly.

Also fixes a minor energy estimation bug in ValidateMultiPQSig.getEnergyForData: the malformed-input fallback was returning MAX_SIZE × WORST_PQ_ENERGY (5 × 470 = 2350), which underestimates the true worst case when all slots are ECDSA (5 × 1500 = 7500). The fallback now uses MAX_SIZE × WORST_ENERGY_PER_SIGN.

Why are these changes required?

The Ethereum precompile address space (0x01–0xff) is continuously being allocated by new EIPs. Placing TRON PQC precompiles at 0x16–0x1a risks future conflicts. The 0x02000000 namespace provides a TRON-specific range that will not clash with Ethereum assignments.
