feat(reports): add automation percentage to summary table

Move automation percentage from Bot Activity section to summary table
for better visibility. Shows percentage and full breakdown (245 bot PRs
out of 389 total PRs) to give immediate insight into automation levels.

Resolves pending todo: simplify bot activity table visibility.
