Improves guidance for eQSL mappings by adding a shared-account tip, making the password field label/placeholder explicit about blank-password reuse, and clarifying that passwords are only required for new usernames. The eQSL wiki guide was updated to match this behavior and include a troubleshooting check for first-time username setup.
Refactor eQSL batch update to operate on resolved primary keys instead of re-matching QSOs by time/callsign/band/mode. Eqslmethods_model now queries current eQSL status by COL_PRIMARY_KEY, builds update batches keyed by primary key, and returns updated_ids and duplicate_ids. This avoids re-querying with un-normalized ADIF modes, improves reliability (avoids CI3 affected_rows() pitfalls), and makes duplicate detection deterministic. EqslImporter was updated to enqueue qso_id for batch updates and to mark QSOs as Updated or Already received based on the returned ID lists.
Add batch processing for eQSL imports/exports and introduce performance indexes. Bump migration_version to 248 and add Migration_add_eqsl_performance_indexes to create idx_eqsl_qslrdate and idx_eqsl_confirmation_match indexes to speed up eQSL queries and batch matching. Modify Eqsl controller to collect successful uploads and perform a single batch mark-as-sent update. Update EqslImporter to queue confirmations and run a single batch update at the end. Implement eqsl_update_batch() and eqsl_mark_sent_batch() in Eqslmethods_model to perform efficient batch DB operations and logging, reducing per-record queries for large eQSL operations.
Thanks to M0TAZ for requesting this option, if you have lots of QSOs on a fresh install, use this function to mark all QSOs as uploaded to eQSL when you manually upload ADIF to eQSL.
