Match platforms listed on taler.net/wallet (including Ubuntu Touch).
Each mark is dual-coloured gold (#f0c86a) and blue (#3ecfbf) for
readability on dark landings. Edge/Brave removed (not listed there).
Applies to bank, exchange, and merchant wallet hubs.
Wallet hub rows on bank, exchange, and merchant landings used vague mono
icons that were hard to tell apart.
Replace them with multi-colour brand-style marks for Chrome, Firefox, Edge,
and Brave. Hub label becomes “Web browsers (experimental)”.
Also drop the circled “①” prefix from the shop pay popup “Wallet payment”
label — leftover copy-paste artefact from an earlier draft, not intentional
numbering.
