REPLAY-1902 Make SR uploader even more eager

[ncreated]

What and why?

⏱️ Following on #1363, we want to make SR uploader even more eager.

The rationale is to leverage -beta and to promote data consistency over uploads performance slightly more. After getting numbers with next observability tasks, we will lower the preset to more optimised one.

How?

We're leveraging the performance preset override API added earlier. I selected new values by testing in example project - playing smooth scenario and adjusting numbers to achieve relatively short batch buffer.

Review checklist

• Feature or bugfix MUST have appropriate tests (unit, integration)
• Make sure each commit and the PR mention the Issue number or JIRA reference
• Add CHANGELOG entry for user facing changes

Custom CI job configuration (optional)

• Run unit tests
• Run integration tests
• Run smoke tests
