feat: improve query performance for manage permissions

[paustint]

Queries are now paginated by DurableId so we no longer need to rely on Salesforce query pagination which is very limited for EntityParticle

[Copilot]

Pull request overview

This PR improves Manage Permissions query performance by switching EntityParticle fetching away from OFFSET-based pagination (limited to OFFSET 2000) to keyset pagination using a DurableId cursor, and by adding a shared request-level concurrency limiter to prevent request floods while keeping overall loads fast.

Changes:

• Added a reusable createConcurrencyLimiter utility (with tests) to cap in-flight async work across multiple query groups.
• Introduced queryAllUsingCursor for keyset pagination on a strictly increasing cursor field.
• Updated Manage Permissions EntityParticle query construction and data-loading flow to page by DurableId and share a single concurrency limiter across all requests.

• waitingForSlot.shift() is O(n) because it has to reindex the whole array each time a task finishes. If a caller queues a large number of tasks (which is exactly when a limiter is most useful), this can turn into avoidable quadratic overhead. Consider switching to a simple head-index queue so releasing a slot is O(1).

      runningCount--;
      waitingForSlot.shift()?.();
