Pull request overview

This PR updates CCIP FeeQuoter logic to better account for Sui-specific message execution overhead (receiver object IDs and token-transfer payload sizing) in fee quoting and max_data_bytes validation, and adds Move tests to cover the new billing/validation behavior.

Changes:

• Add Sui-specific payload overhead constants and validation (receiver object ID count/length, expanded payload sizing) to FeeQuoter.
• Update get_validated_fee to incorporate Sui payload overhead into billing calculations.
• Add a dedicated Sui fee billing test module covering overhead increases and revert cases.

• The mock FeeQuoter reports FeeQuoter 1.6.2 but the production ccip::fee_quoter still reports FeeQuoter 1.6.1 even though this PR changes fee validation/billing behavior. Align the version strings (and any version assertion tests) so deployed and mock implementations don’t diverge unexpectedly.
