Remove Kusama relaychain tests

[rockbmb]

Closes #436 .

• Fix KAH proxy tests
• Disable Kusama balances.burn tests
  • Their failure is abnormal; see Issue with burning funds on Kusama relay chain paritytech/polkadot-sdk#9986
• Fix Kusama relay proxy tests
  • All proxy types' allowed calls are drastically restricted; remaining calls are utility, multisig, proxy
• Disable failing XCM tests pending further investigation

now transfer KSM with AH as reserve means there won't be UMP but HRMP instead. so we need to update related tests

[rockbmb]

@xlc can you confirm that

1. tests involving assetHubKusama will go from using HRMP to using UMP/DMP
2. tests with kusama will go from UMP/DMP to HRMP

[xlc]

the core change is the reserve chain of KSM is moved from Kusama to KAH. This means two parachains reserved transferring KSM should use HRMP instead of UMP/DMP

[rockbmb]

@xlc kusama.shiden is failing with RpcError: 1010: {"invalid":{"exhaustsResources":null}}.

Do the Kusama relay tests also need an update, or is this unrelated?

[xlc]

I will say ignore failing one and put them into an issue and then check them later one by one.
KSM transfer between relay to para should work but it is not wrong if it stops working if the parachain decides to stop support such case

[rockbmb]

Failing XCM tests disabled for now; all that's left is to disable the two burn tests that uncovered paritytech/polkadot-sdk#9986

@xlc ready for review

The pull request has two issues. A TODO was found in packages/kusama/src/kusama.proxy.e2e.test.ts that needs to be addressed. The script scripts/check-proxy-coverage.ts is using incorrect proxy types for assetHubKusama.

There is a TODO comment indicating that the configuration for the Auction proxy type is incorrect. This should be addressed, or a ticket should be created to track this issue.

scripts/check-proxy-coverage.ts:83

The assetHubKusama network is configured to use AssetHubPolkadotProxyTypes for checking proxy coverage. It should be using AssetHubKusamaProxyTypes as defined in packages/shared/src/helpers/proxyTypes.ts.
