fix: restore corrected TRX icon file (lost in the compat revert)

Static asset, unrelated to the chains.json schema/parsing incompatibility
that forced master back to 7a087cf - the live app's chains.json doesn't
reference this file right now (no Tron chain config), so it's inert for
production, but pending/post-fix-release's config (and the eventual
coordinated release) already points at this exact path.
