fix(gift): working bot deep-link + desktop layout + barrel icons

- Build the share deep-link as t.me/<bot>?start=GIFT_<code> (literal underscore). The old GIFT%5F encoding was passed to the bot verbatim by Telegram, so its startswith('GIFT_') never matched and activation silently failed.
- Source the bot username from the runtime branding config (env var is only a fallback), so the 'activate via bot' line no longer vanishes on builds without VITE_TELEGRAM_BOT_USERNAME.
- Widen the page on desktop (max-w-2xl) and show sent gifts in a 2-col grid; it was cramped to a mobile column.
- Replace the remaining hand-written SVG icons with the central barrel.
