Fix Azurite Table/Queue services not starting during durable function debugging

[Copilot]

When debugging durable function projects and selecting "Run Emulator" in the prompt dialog, only the Azurite Blob service was being started. This caused durable functions to fail during execution because they require all three Azurite services (Blob, Table, and Queue) to function properly.

The issue was in the validateEmulatorIsRunning function in src/debug/validatePreDebug.ts, which only executed the azurite.start_blob command when users clicked "Run Emulator".

Root Cause:
Durable functions rely on:

• Table storage to persist orchestration state and execution history
• Queue storage for reliable message delivery between orchestrators and activity functions
• Blob storage for checkpointing and general file storage

Starting only the Blob service left the Table and Queue services unavailable, causing connection errors when durable functions attempted to access these services.

Solution:
Modified the emulator startup logic to start all three required services:

// Before (only blob service)
await vscode.commands.executeCommand('azurite.start_blob');

// After (all required services)
await vscode.commands.executeCommand('azurite.start_blob');
await vscode.commands.executeCommand('azurite.start_table');
await vscode.commands.executeCommand('azurite.start_queue');

Benefits:

• Durable functions now work immediately after clicking "Run Emulator"
• Improves development experience for all function types that use Table/Queue storage
• Maintains backward compatibility
• No breaking changes - only adds functionality

Fixes #4551.
