chore: limit graphColorMapping to CLOUD

[wdoconnell]

Part of #6307

@jeffreyssmith2nd traced this bug to this PR adding color persistence features (graphColorMapping) to UI visualizations. It was part of this epic.

#5233 removed feature flag protection on that feature, resulting in it becoming part of the UI codebase for OSS and Cloud. It's causing serious visualization rendering issues in OSS (but not CLOUD, seemingly). To unblock the OSS team, which has the UI pinned to an older version to resolve this issue, we're going to proceed without the graphColorMapping feature in OSS, at least for now, so that OSS doesn't need to stay pinned to an outdated UI.

Hey @wdoconnell, is there anything needed from my end to help get this PR merged? I'd love to get it into the 2.7 release of InfluxDB (date TBD) if possible.

Hi @jeffreyssmith2nd - this needs some additional testing, which I expect to be able to get to this week (likely Thursday/Friday). If no issues arise we should be able to merge it then.

Great, thank you @wdoconnell!

@jeffreyssmith2nd Due to some reprioritization of golang work in granite work, testing of this is likely moved to early next week.

If I'm still able to get through testing of it this week, I'll let you know. 🙏
