TMDM-7137: "Staging validation deleted the Product family failed if it was used in master"
TMDM-7614: "Translation for new 'delete failed due to constraint issue'"

Adds new staging constant 405 (deletion failed due to constraint issue).
Updates web application tool tips for new 405 status (as defined in TMDM-7614).
Updates server-side behavior for 405 instances (retries previously failed deletions during validation).
Fix issue when path to display in web UI includes an internal field (for example: "$staging_status$").
