Incremental Data Caching

Objective

Enable caching of card data to the server incrementally per set when multiple sets are selected, rather than sending a single massive payload at the end. avoiding PayloadTooLargeError.

Implementation Details

1. Helper Function: Created cacheCardsToServer helper within fetchAndParse to handle server communication for a chunk of cards.
2. Incremental Loop: Modified the set fetching loop to call cacheCardsToServer immediately after receiving data for each set.
3. UI Feedback: Updated progress text to clearly indicate when the system is "Caching [Set Name]..." to the server.
4. Error Handling: Added try/catch within the caching helper to prevent a single cache failure from aborting the entire fetch process (logs error to console).

Status

Completed. Large multi-set fetches should now be robust against body size limits.
