polish: improve step names and logging clarity

- Rename step from 'Get dates for last week' to 'Get dates for last 14 days'
- Add consistent warning messages when metrics files are missing
- Use console.warn for missing file scenarios with [parse-metrics] prefix
- Improve debugging visibility for fallback behavior
