Note

Updates useIsInsufficientBalance to include native-token gas and SOL rent checks, handle scientific notation, and adds thorough unit tests across tokens and edge cases.

• Bridge hook useInsufficientBalance:
  • Handle native-token gas by summing sourceAmount + gasFee using quotes.recommendedQuote.gasFee.effective.amount when gasIncluded is false.
  • Preserve SOL rent exemption check using selectMinSolBalance with lamports comparison.
  • Normalize numeric inputs (incl. scientific notation) via BigNumber.js/normalizeAmount; validate decimal precision.
  • Refactor native token detection (isNativeAddress) and branch logic; early-return safeguards for invalid inputs and gasless swaps.
• Tests:
  • Add comprehensive unit tests covering ERC-20 (gasless/cross-chain), ETH/MATIC native gas scenarios, SOL rent exemption, scientific notation, and edge cases (undefined inputs, no quote, zero balance).
