feat: Adds Bar chart migration logic

[michael-s-molina]

SUMMARY

This PR adds the Bar chart migration logic (legacy ➡️ ECharts). Users can execute this migration using the CLI command and disable the legacy version with the VIZ_TYPE_DENYLIST configuration. Both Bar Chart (legacy) and Time-series Bar Chart (legacy) can be migrated using this command.

Note: Given that the Bar Chart (legacy) supports multiple values in the x-axis and the ECharts version supports a single value, the migration uses the first value in the x-axis and subsequent values as dimensions. For this specific case, the migrated version might look different because it will contain multiple series. Users can manually adjust the chart using a custom SQL if the old behavior is desired.
