Dark Modal UI

New Features

1. Quest search box: A search field at the top of the quest log filters the list in real time by quest name or zone name — handy when you're carrying 20+ quests.
2. Custom quest tracker: A persistent tracker panel on the right side of the screen, replacing the default tracker with the same dark UI style.
   • Shows watched quests with level-colored titles, objective progress, and a gold "ready to turn in" hint.
   • Click a quest title to open the quest log straight to that quest's details.
   • Movable with position memory and off-screen self-recovery; click the header to collapse/expand (anchored to the top edge, no jumping); collapsed state shows the watched quest count.
   • Questie integration: automatically steps aside when Questie's own tracker is enabled, so you never see two trackers.
   • New toggle in the options panel to turn the tracker off entirely.

Fixes & Improvements

1. Reworked quest log selection state: gold accent bar plus a subtle gold tint — the selected quest is now obvious.
2. Fixed quest type tags: normal quests no longer mislabeled as "Daily" (frequency constants corrected: 1 normal / 2 daily / 3 weekly).
3. Fixed group quests (e.g. Ragefire Chasm) not appearing on some clients: quest level/type fields are now normalized to numbers to avoid silent string-comparison failures.
4. Scroll offsets reset on the details and list views for cleaner layout; added a large quest title at the top of the details column.
5. Hardened locale auto-detection to reduce mixed Chinese/English text.
6. Search box no longer overlaps the title; extra bottom padding on the tracker so the decorative border never covers content.
