Re-adds the 'Show data source' tooltip option (General tab, default off),
but accurate this time. The previous version was removed because it
guessed the source from the global data-source mode (showing Learner when
data was AscensionDB, etc.). This tags each pin with its real provenance
at creation and reads that tag.
- QuestieDB.GetPinDataSource(entityType, id, spawnData): resolves
Learner (per-spawn isLearned or learner record), AscensionDB (curated
ascensionOverrideKeys override), or base Questie DB. Never guesses.
- Objective pins tagged per-spawn in _DetermineIconsToDraw; available/
finisher pins defaulted by quest in DrawWorldIcon; manual notes tagged
Townsfolk in DrawManualIcon.
- World-map pins read the per-pin tag (MapIconTooltip); unit/object/item
hovers derive per-id at the render layer (TooltipHandler via
QuestieTooltips:GetDataSourceLine). Comms appended via KeyExists.
- No line shown when source is genuinely unknown (never misleading).
Five Options files seeded their tab tables with { ... } instead of {}.
At chunk scope WoW passes ... = (addonName, addonTable), so each table
got two stray junk entries instead of being empty; { ... } is also a
strict Lua 5.0 parse error. Fixed QuestieOptions.tabs and the Arrow,
General, Keybinds, and Tracker tab tables. Cherry-picked from
phase2-lua50-sweep (the only version-independent fix in that branch).
