Help avoid dismantling items that are propping up your drop power

[bhollis]

In The Final Shape, power levels will once again be rising, and the power grind will be resumed. During this phase, it's important to keep the items that make up your maximum power set - if you accidentally dismantle one, your "drop power" decreases and new drops won't necessarily continue to increase your power.

We should offer some help to prevent accidentally deleting items that are in this set. This could take the form of:

1. Showing a warning if you mark one of these items as junk: https://github.com/DestinyItemManager/DIM/issues/6262
2. Highlight the highest power items somehow: https://github.com/DestinyItemManager/DIM/issues/9259
3. Automatically lock/tag highest power items: #7219

One thing to consider is that we should probably be very specific in which items we consider to be "load bearing" to your drop power. e.g. if you have 5 items at the highest power, they maybe shouldn't all be highlighted, but if you go to delete the last one you should get a warning. We should not have a situation where being at the power cap means all your items have some highlight/warning on them. Instead, we should focus specifically on the scenario of "if you deleted this item, your drop power would decrease". As part of that, we should add a search for just these items.

I'm closing some of the linked issues in favor of this tracking issue.

Bungie also stated power is account bound now not character bound.... let me see if I can find that article

Interesting to know! Does that mean we should also update the gear power sheet to show the highest power set across characters?
