KM Koushik 04d0f4b123 feat: support standard AWS env vars and default credential chain (#401)
* feat: support standard AWS env vars and default credential chain

Replace non-standard AWS_ACCESS_KEY / AWS_SECRET_KEY with the AWS-standard
AWS_ACCESS_KEY_ID / AWS_SECRET_ACCESS_KEY. The old names are kept as
fallbacks in the runtimeEnv for backward compatibility.

Both vars are now optional. When omitted, the credentials object is not
passed to SESv2Client, STSClient, or SNSClient — the AWS SDK then falls
back to its default provider chain (IAM roles, ECS task roles, instance
profiles, etc.), which is the recommended approach for cloud-native deployments.

Closes #316

* Potential fix for pull request finding

* refactor: extract shared getAwsCredentialOptions helper and add partial-config guard

- Move the credential spread logic into a single credentials.ts helper
  so SESv2Client, STSClient, and SNSClient all share one implementation
- Throw a clear error if only one of AWS_ACCESS_KEY_ID / AWS_SECRET_ACCESS_KEY
  is set, preventing silent fallback to the default provider chain with a
  half-configured environment

* fix: align AWS env vars in docker and docs

* fix: use alias import for AWS credentials helper
