95461: ui: remove reset sql stats for non-admin r=maryliag a=maryliag

Continuation from #95303

The previous PR missed the reset on the Transactions tab. This PR removes the reset sql stats for non-admin users.

Fixes #95213

Release note (ui change): Remove `reset sql stats` from Transactions page for non-admins.

95466: ingesting: fixup privileges granted during database restore r=rafiss a=adityamaru

Previously, all schemas and tables that were ingested as part of a database restore would "inherit" the privileges of the database. The database would be granted `CONNECT` for the `public` role and `ALL` to `admin` and `root`, and so all ingested schemas would have `ALL` for `admin` and `root`. Since 21.2 we have moved away from tables/schemas inheriting privileges from the parent database and so this logic is stale and partly incorrect. It is incorrect because the restored `public` schema does not have `CREATE` and `USAGE` granted to the `public` role. These privileges are always granted to `public` schemas of a database and so there is a discrepancy in restore's behaviour.

This change simplifies the logic to grant schemas and tables their default set of privileges if ingested via a database restore. It leaves the logic for cluster and table restores unchanged.

Release note (bug fix): fixes a bug where a database restore would not grant `CREATE` and `USAGE` on the public schema to the public role

Fixes: #95456
