feat: Aurora Migration Verification

[r-near]

Description

This PR adds functionality to verify the pause status of Aurora Engine precompiles and ETH connector methods.

Changes

• Added a new checkAuroraPrecompiles function to verify the status of EXIT_TO_NEAR and EXIT_TO_ETHEREUM precompiles
• Implemented ETH connector flags verification to check if ft_transfer and ft_transfer_call methods are paused

Technical Details

• Interprets precompile flags where:
  • EXIT_TO_NEAR = bit 0 (value 1)
  • EXIT_TO_ETHEREUM = bit 1 (value 2)
• Handles ETH connector pause flags:
  • PAUSE_DEPOSIT = bit 0 (value 1)
  • PAUSE_WITHDRAW = bit 1 (value 2)
  • PAUSE_FT = bit 2 (value 4)
• Recognizes special case flag value 255 for pausing all functions

Testing

The verification tool has been tested against Aurora Localnet and correctly identifies the pause status of precompiles and ETH connector methods.
