Inconsistent stringification of numerics between MySQL and ClickHouse drivers

[mzealey]

Describe the bug

When I run a query against ClickHouse, all numerics, measures etc get stringified.

When I run a query against MySQL, the measures at least don't get stringified in the response and are returned directly as JSON integers.

Expected behavior

Given the current docs, I would have expected all numeric responses to be stringified for all DB drivers (but actually I'd prefer it if something like #7118 were implemented)

Version:

Cube 1.1.9
Clickhouse 24.7
Mariadb 10.11.7
