fix(map): pixel-snap minimap icons to align with native blips at fractional scales (#6)

At fractional UI scales (e.g. 0.71 game scale + Windows display scaling)
the raw fractional pin offset landed icons between physical pixels,
rendering blurry and offset from the engine-drawn native quest blips.
Snap the offset to a whole physical pixel via the minimap's effective
scale so Questie's icons sit on the same grid as native markers.

 ### Bug Fixes
 
+- **[Map - Minimap Icon Pixel Snapping At Fractional Scales]** (#6) Minimap quest icons are now snapped to the physical pixel grid when positioned. At fractional UI scales (e.g. a 0.71 game scale combined with Windows display scaling) the raw fractional offset placed icons between physical pixels, making them render blurry and visibly offset from the engine-drawn native quest blips. Rounding the pin offset to a whole physical pixel (via the minimap's effective scale) keeps Questie's icons on the same grid as the native markers, improving alignment at non-integer scales.
 - **[Map - Hide Callboard Quests: Robust Board Detection]** (#10) The "hide repeatable quests below level 60" option only hid quests flagged repeatable in the DB, but Ascension's Call Board / Contract Board bounties (e.g. NPC 24 "Outlaw's Contract Board") aren't reliably flagged repeatable, so their `!` markers still showed. Added `QuestieDB.IsBoardQuest(questId)` which detects these by their starter NPC/object name containing "board" (cached per quest), and the hide-below-60 option now hides a quest when it is repeatable **or** a board quest — closing the gap in both the available-quest draw path and the icon visibility check.
 - **[Tooltip - ElvUI Style No Longer On By Default]** (#16) The "ElvUI tooltip style" option shipped enabled by default, so Questie restyled every default WoW tooltip — stripping the border — for users who never asked for it and don't run ElvUI. It is now opt-in (default off), and a one-time migration resets it off for existing installs so their default tooltips return. Users who want the flat style can re-enable it in the General tab.
 - **[Quest - Turned-In Quests Misclassified As Abandoned]** (#9) On Ascension some turn-ins (notably crafting/auto-complete quests) fire `QUEST_REMOVED` without a preceding `QUEST_TURNED_IN`, so Questie's 1-second abandon timer ran `MarkQuestAsAbandoned`. By then `QuestLogCache.RemoveQuest` had already cleared the quest, so the `IsComplete` check returned 0 and the *turned-in* quest was treated as abandoned — leaving its objective pins and turn-in `?` lingering on the map and minimap. The completion state is now snapshotted at `QUEST_REMOVED` time (while the quest is still in the cache) and used by the abandon timer, so a quest that was complete at removal is correctly completed (pins/`?` cleared) rather than abandoned.
