Add secure connection option for S3

[DanPlayz0]

This PR adds a feature for users who do not want to deal with TLS with S3. This is mostly a feature for self-hosted instances of the bot.

This pull request introduces a configuration enhancement to make the S3 connection security settings configurable via environment variables. The most important changes include adding a Secure field to the S3 configuration structs and updating the S3 client initialization logic to use this new field.

Configuration Enhancements:

• internal/config/config.go: Added a Secure field (type bool) to both the Import and Archive S3 configuration structs. This field is mapped to the SECURE environment variable with a default value of true.

S3 Client Initialization Updates:

• cmd/import/main.go: Updated the s3ImportClient initialization to use the config.S3.Import.Secure field instead of a hardcoded true value.
• cmd/import/main.go: Updated the s3ArchiveClient initialization to use the config.S3.Archive.Secure field instead of a hardcoded true value.
