fix: Viz migration adjustments - 1

[michael-s-molina]

SUMMARY

Makes adjustments to the viz migrations to fix problems found during tests.

• Adjusts the Pivot Table migration to account only for the column totals instead of rows and columns given that the legacy chart didn't support row totals.
• Adjusts the Pivot Table to sort the rows by descending values given that this was the original algorithm in the legacy version.
• Adjusts the Dual Line migration to account for the GENERIC_CHART_AXES feature flag.
• Adjusts migrations that contain a X-axis control to set the time grain as Day by default if none is provided
