Subject: [PATCH] Add extended dashboard metrics and helpers

Extend FetchDashboardData to collect additional metrics: tool executions, addon installations, GPU usage (including passthrough), error categories, and install durations for averaging. Populate new Dashboard fields (GPUStats, ErrorCategories, TopTools, TopAddons, AvgInstallDuration) and add helper builders (buildGPUStats, buildErrorCategories, buildToolStats, buildAddonStats) that sort results and trim to top-N where appropriate. Keeps existing daily stats and recent records logic unchanged.
