Unnecessary full-table scan in AggregateCompanies: record fetch runs when only totalCount needed

https://sonarly.com/issue/14733?type=bug

The `AggregateCompanies` GraphQL query requests only `totalCount`, but the server unconditionally executes a record-fetching query (`SELECT id ... LIMIT 201`) taking 1730ms, in addition to the efficient 44ms `COUNT(*)` query that actually provides the result.

Fix: Skip the expensive record-fetching `queryBuilder.getMany()` call when the GraphQL query only requests aggregate fields (like `totalCount`) and no record fields.

The `AggregateCompanies` query requests only `totalCount`, which is parsed into `selectedFieldsResult.aggregate`. The `selectedFieldsResult.select` and `selectedFieldsResult.relations` are both empty. Despite this, the code unconditionally ran `queryBuilder.getMany()` fetching up to 201 records — a 1730ms full-table scan on large workspaces — then discarded the results.

The fix adds a `hasRecordFields` check (mirroring the existing `hasAggregatedFields` pattern from commit `1decd40eea`) that gates the entire record-fetching block. When only aggregate fields are requested:
- `buildColumnsToSelect`, `setFindOptions`, `take`, and `getMany` are all skipped
- `objectRecords` defaults to `[]`
- `getPageInfo` handles empty arrays gracefully (returns null cursors)
- The aggregate query (`COUNT`) still runs as before

This eliminates the 1730ms unnecessary query for aggregate-only requests while preserving all behavior for normal findMany queries that request record fields.
