Pagination on audit logs

[nhoening]

Audit logs will grow (for active assets and accounts).

We should use pagination in the endpoints for asset and user

The endpoints are one part, making the data tables use pagination is the other. It should just be busy work, as we have done so already for the asset list and user lists.

Searching audit logs is of course useful, I suggest searching the action description and user name.

This can happen in two PRs, tackle asset audit log first in that case.

P.S. Also set "User" and "Asset" resource in the docstring, so that in this table, the endpoints are listed in the right place.
