feat(ui): add Rank column and enable sorting in vector set similarity results

[dantovska]

Summary

• Stamps a 1-based rank on each VectorSetSimilarityMatch in the BE response order (in the slice reducer), so rank stays independent of the table's client-side sort.
• Adds a Rank column rendering a #N badge per row and moves the Similarity column to the rightmost position. Column order is now Element, …attributes(α), Rank, Similarity.
• Enables sorting on the Element, Rank, attribute, and Similarity columns.

Test plan

• Run a similarity search → Rank shows #1, #2, ... in BE order, Similarity column is the last column.
• Click an attribute column header → rows sort by that attribute; Rank badges stay attached to their match (don't renumber).
• Click the Similarity / Element headers → sorting works.
• Toggle attribute column visibility → still works as before.
• yarn test (45 + 58 = 103 tests in scope, all green locally).

Note

Low Risk
Browser-only vector-set similarity UI and Redux shaping; no auth, API contract, or data-mutation changes beyond stamping rank on search success.

Overview
Adds 1-based rank on each similarity match when search results land in Redux (backend response order), so rank stays on the row when the table is sorted client-side.

The results table gets a Rank column (#N badges), Similarity moves to the far right (Element → attribute columns → Rank → Similarity), and header sorting is turned on for Element, Rank, Similarity, and dynamic attribute columns. Attribute sorting uses memoized getParsedAttributes so JSON is not re-parsed on every compare.

Column visibility treats Rank like Element and Similarity (always shown); min-width math includes the new column. Tests cover reducer stamping, column order, and getParsedAttributes caching.

Looks good! 🚀 There are still a couple of valid Cursor suggestions to clean up, but after that, I’m good to approve again.
