feat(stats): add alass sidecar retiming for sentence mining and fix timi

- Retime local English sidecars against the Japanese sidecar via alass before populating sentence card translation fields; cache retimed copies for the process lifetime
- Reject reversed or non-positive subtitle timings in immersion tracker and before media generation
- Fix word card mining so sentence audio goes to SentenceAudio (not ExpressionAudio) and English subtitle text is not written to SelectionText
- Consolidate 10 individual change fragments into stats-updates.md
