fix: backfill Tron address for pre-existing wallets - TRX was invisible for every account created before Tron support shipped

Found via manual device testing against a real, pre-Tron production wallet: TRX/USDT-TRC20 didn't appear anywhere in the Assets list, not even as a zero balance - unlike every other configured chain (KSM, USDC, ETH, BNB, AVAX, LINK all show up at 0). Root cause: MetaAccount.hasAccountIn() gates Tron balance sync on tronAddress != null, but tronAddress is only ever populated once, at fresh-mnemonic-creation time in AccountSecretsFactory.metaAccountSecrets(). The migration that added the tronPublicKey/tronAddress columns (73_74_AddTronSupport) is pure ALTER TABLE like every other migration in this codebase - it never derived a value for pre-existing rows. Net effect: BalancesUpdateSystem silently skips Tron entirely for every wallet that existed before this feature shipped, with zero error surfaced anywhere. No automated test catches this because every automated test creates a fresh (post-Tron) account - this is exactly the class of bug that only manual testing against a real, aged wallet can find. Adds TronAddressBackfillMigration: a one-time, flag-gated pass (mirroring the existing AccountDataMigration idiom) over SECRETS-type accounts that still hold their mnemonic entropy in SecretStoreV2 but have no TronKeypair yet. Derives the Tron keypair via AccountSecretsFactory.chainAccountSecrets (isEthereum=true, same BIP32/secp256k1 path Tron already uses everywhere else) at TRON_DEFAULT_DERIVATION_PATH - the same call fresh-account creation already makes - so a backfilled wallet ends up with byte-for-byte the same Tron address it would have gotten had it been created today, not a separately-reimplemented derivation. Watch-only/Ledger/Json/multisig/ proxied accounts (never had a Tron-capable mnemonic) and raw-seed imports (no entropy) are correctly left untouched, same as they already are for Ethereum. Includes a dedicated unit test asserting the backfill derives the exact same reference Tron address (TUEZSdKsoDHQMeZwihtdoBiN46zxhGWYdH) that TronDerivationTest already cross-validated against live TronGrid data for the standard BIP39 test mnemonic - this touches real wallets' key material, so it's pinned to a known-good vector rather than just asserting against its own output.
