coa.7: guard Skills tab summary against unscanned skill ranks

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.

 Ported for the Ascension CoA (Vol'jin) 3.3.5a client by the Exiles guild. Released as `*-coa.N` tags via Gitea Actions; see `Exiles/coa-altoholic`.
 
+- **3.3.002b-coa.7** — Skills tab: `GetColor()` now nil-safe and the per-skill rank fields (`skillRank1/2`, `cooking`, `firstaid`, `fishing`, `riding`) default to `0` — they're nil for chars `DataStore_Characters` hasn't scanned, which crashed the Skills summary (`floor(rank/…)` arithmetic and the `>= 300` riding check).
+- **3.3.002b-coa.6** — Final straggler: guarded `AccountSharing.lua` realm/name line (name getter was the last `format` arg, so a no-value collapsed it to a format error). Concludes the frame sweep.
 - **3.3.002b-coa.5** — Refactor + completeness pass:
   - Extracted the duplicated character header/row blocks into `Altoholic:AddCharacterTooltipHeader()` and `Altoholic:SetCharacterRowNameLevel()` — the nil-guards now live in one place instead of being copy-pasted across frames.
   - Fixed crash sites the per-frame sweep had missed: `Skills.lua` (row + skill-rank tooltip), `Keys.lua` (×3 `format` with possibly-nil name), and the latent `ShowClassIcons` sort (`Altoholic.lua` — getters bypass their own `or 0` via the DataStore wrapper).
