poc: many strategies pagination (#7011)
This fixes the case when a customer have thousands of strategies causing
the react UI to crash. We still consider it incorrect to use that amount
of strategies and this is more a workaround to help the customer out of
a crashing state.

We put it behind a flag called `manyStrategiesPagination` and plan to
only enable it for the customer in trouble.
