fix: save character name correctly and show story on character sheet

- Load route syncs characterName from Player record so profile updates
  are reflected immediately on next load
- Save route preserves Player record's characterName so auto-saves
  cannot overwrite profile updates
- Public profile response now includes completedChapters
- Character sheet panel displays completed story chapters with outcome
- Removed stale CSS for old achievement/codex toast classes
