🚨 Lighthouse: Parallelize queries in getSchools

[ldsgroups225]

What

Identified an async waterfall in packages/data-ops/src/queries/schools-read.ts where the school list and the total count were being fetched sequentially. This PR parallelizes these independent database calls using Promise.all().

Why

This follows Lighthouse's core directive to 'Parallelize independent database/API calls with Promise.all()'. Executing these queries concurrently reduces the total response time of the getSchools operation.

Impact

Improved database performance for the getSchools read path, making the operation noticeably faster, which benefits any consumer querying for paginated school lists.

📝 Walkthrough

Walkthrough

The getSchools function in the schools-read query module has been optimized to fetch the total count and paginated schools list concurrently using Promise.all, rather than sequentially awaiting the count before executing the list query. The derived calculations and query logic remain unchanged.

Changes

Cohort / File(s)	Summary
Schools Query Optimization packages/data-ops/src/queries/schools-read.ts	Modified getSchools to execute count and list queries concurrently via Promise.all instead of sequential awaiting, improving performance while maintaining the same output behavior.

🐰 A query hops faster today,
Two paths run together in parallel play,
Count and list dance side by side,
No waiting for one—they stride with pride!
