Update a token

Partial update: symbol, name, logoUri (logo), and enabled (kill switch: for a disabled token, transfers are rejected with TOKEN_NOT_FOUND, the webhook ignores events, and new policies/vaults can't reference it; existing data and ledger accounts are left untouched). code/contractAddress/decimals are immutable, since the ledger, policies, and derivation structures reference them.
