Re-runs a Marketing Mix Modeling study previously configured with setup_mmm.
**Important:** Do NOT call this right after setup_mmm. The first run is automatically triggered by setup_mmm. Use run_mmm only to re-launch an existing study later (e.g., after data refresh or parameter changes).
**Prerequisite:** Must have called setup_mmm first to obtain an account_id.
**Duration:** The Meridian fit (MCMC) takes approximately 10-30 minutes depending on data volume. The user will receive an email when results are ready.
**Results:** Results are written to the project's data warehouse (mmm_channel_summary and mmm_weekly_contributions tables). They can then be queried via execute_query.
