Twemoji category icons as logo fallback

For transactions with no brand match, show the spending category emoji
(Twitter Twemoji SVG via jsDelivr) instead of a bare initial:
  Groceries 🛒  Food 🍔  Fuel ⛽  Health 💊  Subscriptions 💻
  Shopping 🛍  Utilities 💡  Cash 🏧  Debt 💳  Wallets 📱  Fees 🏦
Income/transfer rows use flow-type icons (💰 income, 🔁 self-transfer).
Resolution chain: Brandfetch brand logo -> category Twemoji -> coloured
initial. Brand logo onerror also falls back to the category emoji.
Call sites pass {category} (merchants/breakdown) or {flowType} (ledger).
