Cleanup: Remove unnecessary wrapper in log-streams actions

[yimsk]

Summary

Remove unnecessary 1-line wrapper function in log-streams actions for consistency with log-groups.

Current Code

custom/cloudwatch/log-streams/actions.go:37-39

func getCloudWatchLogsClient(ctx context.Context) (*cloudwatchlogs.Client, error) {
    return cwClient.GetLogsClient(ctx)  // Just passes through
}

Called only once on line 47:

client, err := getCloudWatchLogsClient(ctx)

Proposed Change

Replace with direct call (matches log-groups pattern):

client, err := cwClient.GetLogsClient(ctx)

Why

• Single-use wrapper adds no value
• Inconsistent with custom/cloudwatch/log-groups/actions.go which calls directly
• 3 lines of dead code

Impact

• Lines removed: 3
• Files changed: 1
• Risk: None (behavior unchanged)
