diag: log full/enabled asset list per chain in FullSyncPaymentUpdater

HEZ (native type, assetId 0) on Pezkuwi Asset Hub never gets a System.Account
subscription sent to the RPC at all - no exception, no log, while the other 5
statemine-type assets on the same chain sync correctly. Ruled out via code
reading: enabledAssets() default, AssetSourceRegistry dispatch, type mapping,
Room composite PK. This logs the actual chain.assets contents at the exact
point enabledAssets() is consumed, to see directly whether HEZ is present/
enabled in the runtime Chain object or silently absent before this point.
