Enhancement request - Allow defining columns for left and right table based on the contents of the RTX files

As BSR user I want to limit the columns displayed in the left and right tables in 2-sided recon to only those present in the RTX files. Currently all available columns are shown.

Acceptance Criteria:

• 2 new optional out parameters LEFT_LINE_ITEM_COLUMNS / RIGHT_LINE_ITEM_COLUMNS on the reconciliation process job which hold the names of the columns present in RTX

• 2 new optional in non-display parameters on the notification jobs which receive the names of the columns to show

• the new parameters of the notification jobs are preserved in the BSC_Parameter table

• if filled in, the UI shall use the columns from these parameters, otherwise all configured columns shall be used
