Bug 1827811: Plans block

behatnotneeded

The plan block's 'details' link will only display if license metadata is available.
The link will open the modal with licensing information.
Update how the licensemetadata is set in smarty variable.
remove old details link and use new block header instead.
remove the use of modal functionality, block headers & smarty vars
