[AHMP] Post Migration Account Balances of AJUNA NETWORK's Account is weird

Bottom line: the account on AHP was unusable post migration. Even though there was some free balance, we could not transfer any funds as Total Balance = Free + Reserved was smaller than the frozen balance. Transferring 680~ DOT made the account operable again, but of course this can not be the long term solution.

The reserved balance on the RC came from slot leases of the pre-coretime era, so this kind of reserved balance corner case was maybe overlooked during the migration. Additionally, I assume this case did not occur on Kusama as all such reserved balance has been freed already a while ago.

We have a similar issue with Unique Network's account: 14bEKMdGLwGKNTz4BtT7venXZ4RcXdGfBSdEYrJLPNoHRvoK.
Note: this is not a sovereign account, nor a pure proxy. Just a regular account.

It seems that after AHM, it entered an inconsistent state. Now, different apps report different things about the account balance.

• Subscan AssetHub page shows transferrable == 263.45: https://assethub-polkadot.subscan.io/account/14bEKMdGLwGKNTz4BtT7venXZ4RcXdGfBSdEYrJLPNoHRvoK?tab=transfer
• Subscan multi-chain portfolio shows positive wallet value and negative (!) transferable value: https://portfolio.subscan.io/account/14bEKMdGLwGKNTz4BtT7venXZ4RcXdGfBSdEYrJLPNoHRvoK
• The polkadotjs/apps Accounts/Address book page data:

transferable 0.0000 DOT 
vested 0.0000 DOT
locked 144,197.6374 DOT
reserved 143,122.6073 DOT 
bonded 103,122.2063 DOT 

• The system.account storage data:

{
  nonce: 8
  consumers: 5
  providers: 1
  sufficients: 0
  data: {
    free: 2,634,502,483,331
    reserved: 1,431,226,073,757,748
    frozen: 1,441,976,374,128,796
    flags: 170,141,183,460,469,231,731,687,303,715,884,105,728
  }
}

It appears that something is up with the locks/holds/freezes.

Current assumption is that since both accounts were partially migrated, we migrated the complete Locked amount but not the complete Free amount; resulting in the accounts having less transferrable balance on AH post migration.

There are 133 partially migrated accounts, we do have them in a list on-chain. One thing to do would be to deduce the Free RC amount from their AH lock.
