fix: apply the chain/asset-standard label to the main balance list too

The Send/Receive/etc. network picker (NetworkFlowViewModel) already showed
"Ethereum (ERC-20)"/"Tron (TRC-20)" for a multi-chain token's per-chain rows,
but the main Assets dashboard's own expandable per-token breakdown (tap a
token like USDT to see every chain it exists on) is a completely separate
code path (TokenAssetMappers/TokenAssetViewHolder) that still showed a bare
chain name - found via a real device screenshot of that specific screen.

Moved the shared display-name-with-label logic to a public extension
(Chain.displayNameWithAssetStandard(), runtime/ext/ChainExt.kt) so both
screens build the exact same string instead of duplicating (and now
diverging) the same logic twice.
