[Release] PK2 Workbench

Built-in Server Configuration: Open Tools > Server Configuration to edit the Content ID, client version, GatewayServer port, division names, and gateway IP addresses or host names.
Multiple divisions and gateways: Add, update, or remove divisions and gateway addresses from one native dialog.
Automatic saving: Drag-and-drop imports, menu imports, deletions, and Server Configuration changes now save the open PK2 automatically.
Safer edits: Every save keeps the existing .bak backup behavior.
Real-client compatibility: SV.T version editing now follows the genuine Silkroad encrypted-block layout and preserves unrelated file bytes.
