fix(aws): AWS security group rule id fix on the new data model

[balint-tukacs-tc2]

Summary

This PR updates the EC2 security group rules implementation to use AWS's native SecurityGroupRuleId as the unique identifier (instead of a generated one like ruleid = f"{group_id}/{rule_type}/{from_port}{to_port}{protocol}"). This change aligns the data model more closely with AWS's API and simplifies rule identification.

Changes:

• Updated IpRule node schema to use AWS native ruleid (sgr-*) as the primary identifier
• Added arn property to store the full ARN of security group rules
• Added isegress boolean property to IpRule nodes to represent whether rules are inbound or outbound, matching the AWS API response
• Updated and fixed integration tests to verify the implementation
