fix(learner): capture spawn coords via HBD so learner pins persist

GetPlayerCoords used raw GetPlayerMapPosition('player'), which returns
0,0 when the world map isn't on the player's zone (the usual case) and
mis-reports on Ascension subzones like Sunstrider. Learn events captured
no position, so NPCs were saved spawnSource='fallback' with no [7]
spawns and their learner-only pins never persisted -- showing briefly
after a live kill then vanishing. Read from HBD:GetPlayerZonePosition()
(robust SetMapToCurrentZone/Sunstrider-corrected, cached), falling back
to the old API only if HBD is unavailable.

 ### Bug Fixes
 
+- **[Learner - Capture Spawn Coordinates Reliably (Fixes Disappearing Pins)]** The learner's `GetPlayerCoords` used the raw `GetPlayerMapPosition("player")`, which returns `0,0` whenever the world map isn't set to the player's current zone (the usual case — the map is closed or showing another zone) and mis-reports on Ascension subzones like Sunstrider Isle. So kill/mouseover learn events captured no position: NPCs were saved with `spawnSource="fallback"` and no `[7]` spawns, and in learner-only mode their pins never persisted (showing only briefly after a live kill, then disappearing on the next redraw/reload). It now reads position from `HBD:GetPlayerZonePosition()` — the robust `SetMapToCurrentZone()`/Sunstrider-corrected path, cached for cheap per-kill calls — falling back to the old API only if HBD is unavailable. Newly encountered mobs now record real coordinates so their learner pins persist.
 - **[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.
