Address Codex review: truncation from raw count; session list cap

- Use raw messages.length (before NO_REPLY filter) for chatHistoryTruncated
  so a full 25-message page with filtered entries still shows truncation notice.
- Raise sessions.list limit for chat refresh from 40 to 60 so the active
  session is more likely included in the list for metadata (reasoning level, etc.).
