Adds support for configuring a custom SQS base URL via environment/config and uses it when constructing queue URLs for event publishing.

File-Level Changes

Change	Details	Files
Allow SQS queue URLs to be constructed from a configurable base URL rather than a hardcoded AWS hostname.	Introduce a BASE_URL field in the Sqs config type and wire it to the SQS_BASE_URL environment variable with a default empty string. Update the SQS controller to compute a baseUrl from config (falling back to the previous AWS SQS hostname format) and use it to build the final sqsUrl for queues. Document the new SQS_BASE_URL environment variable in the example environment configuration file.	src/api/integrations/event/sqs/sqs.controller.ts src/config/env.config.ts env.example

Hey - I've found 1 issue, and left some high level feedback:

• Consider normalizing BASE_URL (e.g., trimming any trailing slashes) before concatenation so that sqsUrl is well-formed and doesn't end up with // when a trailing slash is present in the env var.
• You may want to treat BASE_URL as optional in the Sqs type (e.g., BASE_URL?: string) and centralize the defaulting logic in ConfigService so that consumers can assume a non-empty, fully-formed base URL.

**suggestion:** Handle potential trailing slashes in `BASE_URL` to avoid double slashes in the final SQS URL.

If `SQS_BASE_URL` includes a trailing slash (e.g. `https://sqs.us-east-1.amazonaws.com/`), `sqsUrl` will end up with a double slash before the account id. Please normalize `baseUrl` first (e.g. strip a trailing `/` or use a helper to safely join URL segments) before building `sqsUrl`.

```suggestion
            ? 'singlequeue'
            : `${event.replace('.', '_').toLowerCase()}`;
        const queueName = `${prefixName}_${eventFormatted}.fifo`;
        const rawBaseUrl =
          sqsConfig.BASE_URL || `https://sqs.${sqsConfig.REGION}.amazonaws.com`;
        const baseUrl = rawBaseUrl.replace(/\/+$/, '');
        const sqsUrl = `${baseUrl}/${sqsConfig.ACCOUNT_ID}/${queueName}`;
```
