feat: add VPC creation tool for AWS resource automation with MCP

[socrativejh]

What does this PR do?
• Adds a createVpc tool to allow users to create AWS VPCs via MCP prompt-based commands.
• Increases Lambda timeout to 900 seconds and adds necessary EC2 permissions to support VPC creation.

⸻

Why is this needed?
• While MCP currently supports observing AWS resources, adding creation capabilities expands its practical use in real-world environments.
• Users can now automate AWS environment setup directly via MCP, improving onboarding and hands-on cloud learning workflows.

Background
• I recently completed my internship as a Cloud Support Engineering Intern at AWS Korea (Dec 2024 - June 2025).
• During my internship, I used your MCP open-source project in several internal learning and automation projects, which greatly helped me learn AWS resource management.
• I would like to share back this example contribution to express my gratitude and to help expand MCP’s usage.

How to use
• Example prompt:

createVpc(params={"cidr_block":"10.10.0.0/16","az_list":["us-west-2a","us-west-2b"],"public_subnets_per_az":1,"private_subnets_per_az":1,"name_tag":"mcp"})

The tool will create a VPC with public and private subnets across the specified AZs.

Changes
• server-http-python-lambda/server/app.py: Added createVpc tool with VPC creation logic.
• server-http-python-lambda/template.yaml: Increased Lambda timeout to 900 seconds and added necessary EC2 permissions for VPC creation.
