Ali Waseem a70264c8ad fix(studio): coerce index advisor cost values to numbers (#44397)
## Summary

- Coerces `before`/`after` cost values to `Number()` in
`QueryPanelScoreSection` and `calculateImprovement` before any
comparison or arithmetic
- Fixes contradictory index advisor display where correct cost numbers
showed 0% improvement and wrong arrow direction

## Root Cause

When `index_advisor_result` is prefetched from the Reports SQL query
(via `json_build_object`), cost values can arrive as strings instead of
numbers. JavaScript string comparison is lexicographic, producing wrong
results:

| Expression | Numbers | Strings |
|---|---|---|
| `after > before` (arrow) | `50 > 100` → `false`  | `"50" > "100"` →
`true`  |
| `costBefore <= costAfter` (improvement calc) | `100 <= 50` → `false` 
| `"100" <= "50"` → `true`  |

The direct fetch path (`retrieve-index-advisor-result-query.ts`)
validates through Zod and is unaffected. Only the prefetched path lacks
validation.

## Summary by CodeRabbit

* **Bug Fixes**
* Improved numeric value handling in query performance calculations to
ensure more accurate and reliable improvement metrics.

* **Refactor**
* Enhanced type safety and numeric coercion for query performance score
comparisons, resulting in more consistent and robust metric
calculations.
