- 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.
DataStore char-based getters return *no value* for any module that hasn't
scanned a given char (DataStore.lua: 'if not arg1.lastUpdate then return end').
Fresh CoA alts have partial per-module data, so the frames crashed feeding
'no value' into format()/concat/arithmetic/pairs. Guarded every such site:
AccountSummary, Activity, BagUsage, Quests, Reputations, TabCharacters,
DrawCharacterTooltip, recipe tooltip. No DataStore contract change.
