refactor: extract API actions into BoxingApiActions with error handling
Centralize all API call logic (fetchBoxInfo, saveBoxRecord, updateBoxRecord, deleteBoxRecord) into BoxingApiActions class with unified error categorization (network, duplicate, missingApiUrl). Add helper methods to reduce repetitive error handling in boxing_page. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
