EPG_PROGRAM_BATCH_SIZE and STALKER_GUIDE_PROGRAM_BATCH_SIZE increased from 500 to 5000, reducing SQLite transaction overhead by 10x during EPG data ingestion. Each batch insert now commits 5000 rows instead of 500, significantly reducing total sync time for large EPG datasets.

Increases EPG_PROGRAM_BATCH_SIZE and STALKER_GUIDE_PROGRAM_BATCH_SIZE from 500 to 5000 rows per transaction.
During EPG sync, XMLTV programs are stream-parsed and inserted in batches. Each batch runs a separate SQLite transaction. With 500 rows per batch, a large EPG dataset (e.g. 300K programs) requires 600 transactions. Increasing to 5000 reduces this to 60 transactions — a 10x reduction in transaction overhead.
