This proposal does two things:

1. It moves 5 million DOT to Asset Hub into the Treasury's account. This is a simple move from Relay to Asset Hub. This move was tested with the KSM Treasury in [Kusama 370](https://kusama.polkassembly.io/referenda/370). This will enable new spend patterns like staged payouts, as demonstrated in [Kusama 382](https://kusama.polkassembly.io/referenda/382).
2. It sets asset rates the same as [Polkadot 645](https://polkadot.polkassembly.io/referenda/645), but under XCM v4. Normally, these should have been migrated with the switch to v4, but since the referendum was open when the upgrade happened, there was nothing (yet) to migrate.

Requires whitelisting from the Fellowship.
