Chainflip added Tron support with asset ids trx.tron and usdt.tron. Enable both for swaps in the Chainflip provider. Tron needs explicit handling because Chainflip's network slug is 'tron', while Cake uses the 'TRX' tag (and null for native TRX), so the generic title.tag normalization can't produce the right ids: - _supported: add trx, usdttrc20 - _normalizeCurrency: map trx -> trx.tron, usdttrc20 -> usdt.tron - _normalizeNetworkName: TRON -> Tron (status lookup in findTradeById) - _toCurrency: reverse-map trx.tron/usdt.tron for trade resolution Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Description
Chainflip recently added Tron support — native TRX (asset id
trx.tron) and USDT on Tron (asset idusdt.tron). This enables both for swaps in the Chainflip provider.Tron needs explicit handling because Chainflip's network slug is
tron, while Cake uses theTRXtag (andnullfor native TRX), so the generictitle.tagnormalization can't produce the correct asset ids.Changes
