1. After moving read databases call to RP for Tables API, we lose the `_rid` property. Since we are reading Table's database offer with SDK, we need the `_rid` of the database to find its offer. Without `_rid`, we won't be able to find the database offer and the Scale tab would disappear again. The fix is to use SDK to read databases for Table API so we have `_rid`.
2. There's a bug in the non-aad code path for updating offers which prevents users from switching from manual to autoscale and vice versa. The fix is to properly set the option headers.
