Agreement content KBART export | correct coverage information

On export of an Agreement content as KBART (e.g. using https://folio-snapshot-okapi.aws.indexdata.com/erm/sas/f007a2f3-6cb0-48bf-8321-91e0f02dd126/export/kbart) the export does not populate:

• num_first_vol_online
• num_first_issue_online
• num_last_vol_online
• num_last_issue_online

These should be populated based on the PCI or custom coverage (as appropriate) startVolume, startIssue,endVolume,endIssue respectively.

The KBART coverage also currently does not choose the correct coverage for the PCI (PCI or Custom coverage) on export, with the current situation that multiple lines are output in KBART for different coverage statements - PCI, Custom, PTI

Only applies to KBART export.
