Add Tron (TRC20/TRX) send/transfer support

Browse Source 
Reuses the existing generic fee-sufficiency validation
(sufficientTransferableBalanceToPayOriginFee) and send flow
unchanged. Transaction construction goes through TronGrid's own
createtransaction/triggersmartcontract endpoints (verified live
against Shasta testnet) rather than a hand-rolled protobuf
implementation; signing reuses the existing secp256k1 path
(SignerPayloadRaw.skipMessageHashing) already used for Ethereum,
no new crypto library. Also fixes a Phase 1 gap: Chain.isValidAddress()
had no isTronBased branch, so every Tron send would have failed
address validation.

No Energy staking/delegation/rental UI - only Tron's default
protocol behavior (burn TRX to cover Bandwidth/Energy shortfall).
