perf: de-select unnecessary columns

[gtarpenning]

https://wandb.atlassian.net/browse/WB-20367

This pr:

• explicitly selects columns from the backend (which de-selects costly input/output fields)
• the result should be much speedier loading in the detail view, and much less data transferred over the wire, with a tradeoff that it will be slower when clicking between items in the tree

Depends on this core fix: https://github.com/wandb/core/pull/23560

In master, loading this trace (peek) takes 3s and loads 26MB in this proj

In this branch, loading the same proj detail trace tree loads 5.5KB in 800ms

In larger projects with huge input/output shapes, this discrepancy is much larger
