Add generic Map API for addon web-map integration

[tastybento]

Summary

• Add MapHook abstract class (api/hooks/) defining a common contract for web-map plugins: marker sets, point markers, area markers, and polygon markers using only JDK/Bukkit types (java.awt.Color, Location, World)
• Add MapManager facade (managers/) that fans out calls to all active MapHook implementations, with try-catch isolation per hook and silent no-op when no map plugins are installed
• Refactor BlueMapHook and DynmapHook to extend MapHook instead of Hook
• Wire MapManager into BentoBox.java — addons access it via BentoBox.getInstance().getMapManager()
• Native API accessors (getBlueMapAPI(), getMarkerAPI()) remain for direct access when needed

Addon usage example

MapManager maps = BentoBox.getInstance().getMapManager();
maps.createMarkerSet("warps", "Warps");
maps.addPointMarker("warps", "warp_123", "Player's Warp", location);
maps.addAreaMarker("warps", "zone_1", "Safe Zone", world,
    0, 0, 100, 100,
    new Color(51, 136, 255),        // blue border
    new Color(51, 136, 255, 38),    // 15% blue fill
    2);

Test plan

• MapManagerTest — fan-out to multiple hooks, silent no-op, exception isolation (14 tests)
• BlueMapHookTest — existing + new abstract method tests (21 tests)
• DynmapHookTest — existing + updated API tests (20 tests)
• Full build passes
