feat: add typed wallets.tron() interface for signTransaction and sendTransaction

Adds PrivyTronService with typed methods mirroring the existing
wallets.ethereum() and wallets.solana() pattern:

- wallets.tron().signTransaction(walletId, input) - signs a Tron
  transaction without broadcasting
- wallets.tron().sendTransaction(walletId, input) - signs and
  broadcasts a Tron transaction

Both methods leverage the existing typed Tron RPC schemas
(TronSignTransactionRpcInput, TronSendTransactionRpcInput) and
route through the standard wallets.rpc() infrastructure.
