fix(stepfunctions): Add document URI check for save telemetry and enable deployment from WFS

[l0minous]

Problem

• Save telemetry was being recorded for all document saves in VS Code, not just for the active workflow studio document.
• Save & Deploy functionality required closing Workflow Studio before starting deployment

Solution

• Add URI comparison check to ensure telemetry is only recorded when the saved document matches the current workflow studio document.
• Refactored publishStateMachine.ts to accept an optional TextDocument parameter and updated activation.ts to support new interface
• Removed closeCustomEditorMessageHandler call from saveFileAndDeployMessageHandler

nit: even this should work fine

await publishStateMachine({ awsContext outputChannel, region })

not a blocking comment
