feat(dynamic-sampling): add sliding window calculation to per-org

[shellmayr]

• Sliding window retrieves the total 24h volume, extrapolates to the monthly volume, and then gets the sample rate from getsentry's tier system
• If available, this sample rate is used as the base for project sample rates for the automatic configurations
• Add the sliding window calculation to the new per-org pipeline
