Add structured log for infinite scroll next page fetch with cursor and result count

[Chucks1093]

Summary

When infinite scroll triggers a next page fetch on the creator list, there is no log to confirm the fetch fired or how many results were appended. A debug-level log should be emitted after each successful next page fetch so developers can verify scroll-triggered pagination without network tab inspection.

Scope

• Emit a debug-level log after each successful next page fetch with fields: cursor, results_fetched, has_more, fetched_at
• Log emitted only for next page fetches triggered by scroll — not for the initial page load
• Log not emitted in the test environment

Acceptance Criteria

• Log emitted after each scroll-triggered next page fetch
• All four fields present with correct values
• Log not emitted on initial page load
• Log not emitted in test environment

ETA: 12 hours
