refactor: unify core execution flow and rename Manage methods to Run for consistency

[ghost]

This pull request refactors the core dispatch mechanism and unifies the lifecycle management of different modes (server, client, master) by introducing a common Run interface. It also includes minor structural adjustments to improve code maintainability and consistency.

Refactoring and Unification of Lifecycle Management:

• Replaced the coreDispatch function's mode-specific methods (runServer, runClient, runMaster) with a unified approach using a Run interface. The Run method is now implemented for Server, Client, and Master classes, consolidating lifecycle management. (cmd/nodepass/core.go, cmd/nodepass/core.goL14-R31)
• Renamed the Manage method to Run in Client, Server, and Master to align with the new unified interface. (internal/client.go, [1]; internal/server.go, [2]; internal/master.go, [3]

Structural and Functional Enhancements:

• Added a tunnelListener field to the Common struct for managing tunnel listeners, and updated the stop method to ensure proper closure of this resource. (internal/common.go, [1] [2]
• Removed the redundant tunnelListener field from the Server struct, as it is now managed centrally in the Common struct. (internal/server.go, internal/server.goL22)
