Rename TAO column accountid to account_id

[CorinneVerheyde]

In ta-organizational-view of the TAO dashboard, the account id column is named "accountid" whereas in the other CID dashboards it is "account_id".

Our usecase is to set up RLS on all CID dashboardw with the same generated CSV and same RLS dataset, which should then match on the same column name.

Could you rename the column in TAO or add a new column with the correct name?
