feat(studio): save an experiment's column layout (ASE-425) - #1738

Conversation
The evaluations table's column order lived in localStorage, so it followed the browser rather than the experiment it describes — which of an experiment's evaluators are worth a column, and in what order they read, is a property of the experiment, not of the machine looking at it. Column visibility was not persisted at all. Store both on the experiment. `ExperimentGroup` gains a `column_layout` holding the column order and the hidden column ids; the entity store is schema-on-read, so no migration is needed. Update follows `pareto`: an omitted `column_layout` preserves what is saved rather than clearing it. The field is nullable so "never saved" stays distinct from "saved with nothing hidden" — the client applies its own default hidden columns only in the null case, so a deliberate "show everything" survives a reload and the Save button does not appear on a freshly loaded page. Visibility is stored as the hidden ids rather than a map over every column, so a column that appears later (a new evaluator, a new metadata key) shows up by default instead of being invisible because a layout saved before it existed never mentioned it. In Studio, a Save columns button appears at the toolbar's leading edge once the live layout differs from the saved one, and disappears again once it matches. `StudioDataViewToolbar` gains an additive `slotStart` to host it. This replaces the localStorage persistence (`nemo-studio:experiment-columns:<id>`), so an existing local layout resets once to the experiment's saved layout.

Suggested reviewers: Merge Risk: 🔵 Low · up to The PR saves experiment-specific column layouts and restores them across sessions, but clients that send an explicit null to clear a saved layout may instead leave the previous layout unchanged because the API contract and update behavior disagree. The change is otherwise mergeable with explicit owner awareness and follow-up to align null handling and the published schema. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

changed the title
Saving a column layout sent the whole experiment back, echoing this client's copies of description, insight_id, summary, metadata and default_sort. Any of those changed since the group was loaded was overwritten by the stale value. The endpoint blanked those five when they were omitted, which is why the client echoed them. Guard them on `model_fields_set`, as every field added since already is, so a caller can update one field without touching the rest; an explicit null still clears. The layout save now sends only `column_layout`. Also key ExperimentDataView by group id: the route does not remount between experiments, so the next one inherited the previous column order and visibility. Mark `column_layout` nullable on the response so generated clients represent the null the API actually returns — which surfaced that the seeding helpers only accepted `undefined`.

Inserting toolbarSlotStart above toolbarSlotEnd left the existing trailing-content doc attached to the new leading slot. Signed-off-by: Rob Rhyne <rrhyne@nvidia.com>
