Add rare mob search with auto-tracking

[wowaddonmaker]

Summary

• Rare mob tracking via vignette API: search "rare" in zone bar or enable auto-track to always show active rares on the map
• Auto-track toggle in filter dropdown and Map options tab, with persistent per-zone cache
• Great Vault (Rewards) now searchable, with Adventure Guide fast mode working for all tabs
• Combat lockdown safety, nav waypoint hierarchy fix, and StaticLocations cleanup

Test plan

• Search "rare" in zone bar near active rares, verify pins appear
• Enable auto-track, verify rares show without searching
• Kill a rare, verify pin clears and doesn't reappear
• Search "great vault", verify direct open navigates to Journeys tab
• /reload during combat, verify no errors
• Place a map pin in a far zone, verify minimap arrow follows portal redirects
