TRON WalletConnect Structure Compatibility Update

Description

This PR updates the TRON WalletConnect implementation to align the transaction signing data structures exchanged between DApps and wallets. The change ensures backward compatibility across different versions of the transaction data format. The changes include:

1. Dapp side updates:

   • Added tron_method_version session property to indicate the structure version being used
   • When tron_method_version === "v1", uses the new structure: params = { address, transaction }
   • When tron_method_version !== "v1" or not present, uses the old structure: params = { address, transaction: { transaction } }

2. Wallet side updates:

   • Updated [TronRequestHandlerUtil.ts] to handle both new and old TRON transaction structures
   • Used compatible access pattern: request.params.transaction?.transaction || request.params.transaction

3. Backward compatibility:

   • Ensures that older dapps can continue to work with the updated wallet
   • New dapps using v1 structure will work correctly
   • No breaking changes for existing implementations

fix: return cached TronWeb instance and switch to verifyMessageV2

• always return tronWebTestnet/tronWebMainnet after init to avoid undefined
• add fallback return undefined for unknown chainId
• use trx.verifyMessageV2(message, signature) to verify message

Hi @ganchoradkov,

The TRON RPC documentation has been updated: https://docs.reown.com/advanced/multichain/rpc-reference/tron-rpc

This PR implements backward compatibility for TRON transaction structures. When tron_method_version: "v1" is set in session properties, it uses the simplified format (params = { address, transaction }). Otherwise, it falls back to the legacy nested format (params = { address, transaction: { transaction } }).

Could you please help review the demo code to ensure it correctly handles both transaction formats based on tron_method_version? Thanks!
