Create table in CMDT section of Rollup app

[jamessimone]

The rollup app currently exposes the LWC, rollupForceRecalculationin a tab so that full recalcs can be performed. As part of #59, this app's roles have expanded to also allowing the user to select a given calc item based and have all of the CMDT associated with that have their rollups be initialized.

@jongpie had some great feedback to enhance this component further by displaying a table of the existing CMDT records (and potentially allowing the user to opt into which CMDT rollups were included in the full recalc). I am kicking this over to a new issue because I view it as a nice to have (for now), but I think it would really round up the functionality of this feature nicely.
