feat: order and label per-chain token breakdown by ecosystem + standard

The per-chain list shown when picking an action (Send/Receive/Swap/Buy/Sell/
Gift) for a token that exists on multiple chains (e.g. USDT) now orders
Ethereum and Tron right after the existing Pezkuwi/Polkadot/Kusama priority
chains instead of falling into the alphabetical "everything else" bucket,
and appends a token-standard label - "(PEZ-20)"/"(ERC-20)"/"(TRC-20)" - to
disambiguate which issuance this is, since a bare chain name alone doesn't
convey that.

The label is intentionally chain-specific, not derived from Chain.Asset.Type,
since every Statemine-type chain (Polkadot AH, Kusama AH, Pezkuwi AH) shares
the same asset type but only Pezkuwi AH's issuance needs the PEZ-20 label.
