Research direction

Start by running screenly edge-app run --generate-mock-data with an existing mock-data.yml, then inspect the CLI entry point for this option and how it reads screenly.yml. Trace the mock-data generation path and verify that added, removed, or modified settings are reflected in mock-data.yml without the existing-file complaint.

Written by the indexing model from the issue text.

Description

When screenly edge-app run --generate-mock-data runs, the CLI would complain that mock-data.yml already exists (if so).
For instance, if I added, deleted, or modified (e.g., updating the default value of a setting) a setting in screenly.yml. Running screenly edge-app run --generate-mock-data should modify mock-data.yml.
The --generate-mock-data option could be renamed to --sync-mock-data (or we could keep the former and introduce the latter as a drop-in replacement).
