GetColor() did floor(rank/..) with no nil-guard and riding did 'field >= 300';
skillRank1/2/cooking/firstaid/fishing/riding are nil for chars DataStore_Characters
hasn't scanned. GetColor now defaults rank to 0 and each field falls back to 0.
- 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.
