Part of #2456 - Don't abuse `get_full_accounts` API

Most time when querying for an account, the UI just want to know the account's name and perhaps whether the account is a LTM. In this case, it's better to use `get_objects` API rather than `get_full_accounts` API.

For even better performance, we can add another lighter API to only return the needed data fields, or make a more flexible API so UI can only ask for a subset of data fields.

Start by locating UI account queries that call get_full_accounts and compare their needs with the data returned by get_objects. Determine whether the intended scope is replacing those calls or designing a lighter or field-selecting API. Done should mean the UI requests only the needed account data and the performance impact is verified, but the issue names no files or tests.
