…dwidth Activation was billed as TransferContract byte size (~266) plus 1 TRX, which overstated Testing Day costs. Use create-account Bandwidth from chain params, staked quota only, and a 0.1 TRX shortfall instead.

Let's move these types to types.ts, what do you think?

Why do we need so much code to check activation when we have the isAccountActivated method? Do we really need to fetch transactions and all that? Am I missing something?
Explanation
This pull request updates the account activation fee logic for TRON native and TRC-10 token transfers, ensuring that fee estimation for sending to unactivated accounts aligns with the TRON protocol. Specifically, it distinguishes between using staked Bandwidth (costing 1 TRX + 100 Bandwidth) and burning 0.1 TRX when the sender lacks staked Bandwidth, instead of relying on transaction byte size. The changes also add new constants, improve test coverage, and refactor test cases for clarity and correctness.
Fee Calculation Improvements

FeeCalculatorService.test.tsto cover scenarios for native and TRC-10 sends to unactivated accounts, including cases with and without staked Bandwidth, and with memo fees. [1] [2] [3] [4] [5] [6] [7] [8]These changes ensure more accurate and protocol-compliant fee estimates for TRON account activation scenarios.
