Clean up download ahead logic

Browse Source 
- Remove redundant chapter sorting logic when fetching next chapter(s)
- Remove redundant download queue checks (it'll handle already queued or downloaded items)
- Trigger download ahead when read >= 25% of chapter rather than 20%
- Rely on download cache when checking if next chapter is downloaded to avoid jank (fixes #8328)
