Apply local fixes on top of upstream: tracker desync/drag/title, map icon zoom offset

- Compat/HBD.lua: fix world map pin offset math to account for zoom addons
  (e.g. Magnify) rescaling an ancestor frame instead of WorldMapButton itself;
  cull pins that fall outside the scroll frame's viewport when zoomed
- Compat/Compat.lua: add a short TTL to the chat-parsed objective progress
  cache so a stale entry can't be reapplied to an unrelated quest
- Modules/QuestieLearner.lua: re-point QuestiePlayer.currentQuestlog at the
  rebuilt quest table after invalidating QuestieDB's quest cache, fixing
  Tracker freezing on stale objective progress
- Modules/Tracker/QuestieTracker.lua: fall back to a formatted quest name
  when QuestieDB has no title for a quest (e.g. custom server quests)
- Modules/Tracker/TrackerBaseFrame.lua: force baseFrame movability on drag
  start instead of trusting the async-refreshed IsMovable() state
- Modules/Tracker/TrackerHeaderFrame.lua: wire up drag on the tracker icon
- Modules/Quest/QuestEventHandler.lua: force a full quest log reconciliation
  when the native quest log is opened

Squashed from prior commit-by-commit history to rebuild this working copy
on a clean fork of aron-w/Questie-X (restores the native GitHub fork link).
Per-fix rationale is preserved in project memory
(project_tracker_fixes.md, project_map_icon_offset.md).
