Deprecate column `static_object_token ` from `users`.

Related to #348163 (closed).

In scope of the previous issue we migrated existing auth_tokens to the encrypted field static_object_token_encrypted.

Proposal

1. Set static_object_token encryption strategy to required
2. Ignore column static_object_token
3. Drop temporary index for users

Testing

Please run package-and-qa for regression purposes
