chore: migrated from monolithic aws-sdk v2 to the new modular aws-sdk v3

[alexander-schefe]

migrated from monolithic aws-sdk v2 to the new modular aws-sdk v3. includes many code changes because the whole structure of aws-sdk changed completely.

All local tests like creating new users, writing, refusing, accepting reports, etc. I ran on the localhost site worked without issue, but you never know.

Can't really test the email-pdf thingy with localhost i think.

May need to be reviewed carefully.

Pull Request Overview

This PR migrates the application from the monolithic AWS SDK v2 to the modular AWS SDK v3. This is a significant architectural change that affects how AWS services are imported and used throughout the codebase.

Key changes include:

• Migration from single aws-sdk package to individual service clients (@aws-sdk/client-s3, @aws-sdk/client-ses, etc.)
• Updated API patterns from promise-based .promise() calls to command-based .send() operations
• Improved error handling with try-catch blocks replacing error response checking
