test: add Tron balance integration test

Tron is a REST API (TronGrid), not a Substrate runtime, so it never goes through BalancesIntegrationTest's chainRegistry-based mechanism at all - it had zero CI coverage. This exercises the exact TronGridApi the production app uses for balance reads, via a standalone Retrofit client (TronGridApi isn't exposed through a public feature API for tests to reach through the DI graph). Test account is the mainnet Founder's Tron address, verified live via TronGrid's public API on 2026-07-09: 3,925.23 TRX native + 625,213.92 USDT-TRC20 - substantial real balances, not a guessed or empty account.
