coa.17: comprehensive partial-data hardening + DataStore_Characters login scan + Skills strip cap

- Hardening sweep across DataStore_* (softened crash-asserts in Talents/Containers/Quests
  to graceful nil) + Altoholic frames (guarded remaining getter results).
- DataStore_Characters: scan on login (was ghost-gated -> name/level/class never populated;
  the core 'no character data' cause).
- Skills tab: cap inline professions at 6 (+N) so the strip stops overflowing into Cooking.
