improvements needed for implementations page(s)

[TallTed]

As discussed in 2024-10-22 VC-API call.

e.g., break the bar into a segment/column per suite, and show pass/fail results within each segment for that suite, optimally with either filtration to see only the results for chosen suite(s) or the ability to sort by number of passed tests in chosen suite(s) (knowing that'd probably be just by one suite/column at a time)...

This is just (several) idea(s) that came to mind when looking at the top level bar chart. More ideas (and refinements on these) are welcome within this issue, toward (probably several) eventual PRs.
