Add Lambda Zips to Full Release Flow

[stevedylandev]

Problem

Lambda .zip files are currently stored in a way that GitHub automatically deletes after 90 days.

Proposed Solution

• Add Lambda .zip as a Release Artifact attached to each GitHub Release for permanent storage
• Automatically publish Lambda .zips to a dedicated S3 bucket with consistent naming convention:
  • Include release type (preview/snapshot/full)
  • Include version number/tag
• Update Terraform scripts to reference pre-published .zip files from S3 bucket

Additional Context

• Comment from #1399

the files input of our existing action should do the trick
