fix: activity endpoint returns flat array instead of paginated object

Frontend calls (g ?? []).slice(0,10) on activity data, which crashes
when API returns {total, offset, limit, items} instead of ActivityEvent[].
Changed response_model from PaginatedResponse to List[ActivityLogResponse].
Also fixed .mcp.json Playwright package name.

Verified via Playwright MCP: 0 console errors on dashboard.
