#5558 Adjust map request size dynamically

[akleshchev]

• Instead of always requesting 4x4 regions in a single block, adjust request to get up to 64 regions per message (4 blocks)
• Don't request 'animated' regions, they won't arrive in time.

Pull request overview

Adjusts world map region loading to reduce unnecessary requests during pan/zoom animation and to better utilize the server’s per-message region limit when requesting map blocks.

Changes:

• World map view now uses target pan coordinates (mTargetPanX/Y) when determining which regions to request, avoiding short-lived “animated” loads.
• LLWorldMap::updateRegions now groups contiguous unloaded blocks into variable-size rectangular requests, targeting up to 64 regions per message.
