### What problem does this PR solve? Problem Summary: Snapshot tasks persisted the complete offset provider after every split commit, producing frequent edit logs while the snapshot state kept growing. The previous default snapshot split size also produced too many small snapshot tasks. Natural terminal transitions needed explicit persistence so finished jobs replay with their terminal metadata. This change: - Limits snapshot offset edit logs with a mutable 300-second interval while keeping binlog offset commits immediate. - Increases the default snapshot split size from 8,096 to 40,960 rows, while preserving explicitly configured values. - Removes obsolete snapshot recovery state after the first committed binlog offset for FROM-TO and CDC stream TVF jobs. - Persists natural FINISHED transitions and restores terminal replay fields and callbacks consistently. - Adds focused unit coverage and a MySQL snapshot-only FE restart regression case.
