Frontend: User metrics table - first iteration

Proposal

We need to add a table to the GitLab Duo and SDLC trends dashboard which displays user specific metrics.

We currently have the following data which can be added in the first iteration:

• user.name
• user.lastDuoActivityOn
• codeSuggestionsAcceptedCount
• duoChatInteractionsCount (we can consider skipping this and rather waiting for Duo Agentic chat as that should be GA in %"18.6" )

NOTE: We might be able to move away from aiUserMetics which limits us to the metrics above in favor of the newly created ai_usage_event data which is exposed via aiUsageData. If we can make this shift, we'll be unblocked a lot faster. See #574400 (comment 2800385034) for status of this conversation before starting any work.

We can display data for the past 30 days - the same as we do for the tiles at the top of the page.

Iteration 1	scrolled to bottom (keyset pagination)

The table will need to be sortable by Duo metric and include keyset pagination. Pagination should start after 20 items as mentioned in Pajamas.

Implementation

• Create data source
• Add visualization template to GitLab Duo and SDLC trends dashboard
• Update documentation
