coa.5: refactor char display into guarded helpers; fix missed sites; restore login scan

- Extract AddCharacterTooltipHeader() + SetCharacterRowNameLevel() (Altoholic.lua);
  nil-guards centralized, callers in AccountSummary/Activity/BagUsage/Skills/tooltip.
- Fix sites the manual sweep missed: Skills.lua (row + skill ranks), Keys.lua x3,
  ShowClassIcons sort (Altoholic.lua:705, getters bypass their own or-0 via the wrapper).
- Restore login scan: OnPlayerAlive was ghost-only (fdcb25a) so iLvl never populated;
  now scans once per session. Removed dated DEBUG leftovers.
