BOM parts list support: xref template dispatch and LibertyXref fixes

- LibertyContent: add getXrefListTemplate(), getXrefRecordTemplate(),
  getXrefEditTemplate() for package-aware template dispatch with liberty fallback
- LibertyXref: explicit xorder passthrough in verify(); fix start_date/end_date
  to use time() instead of mDb->NOW() so BitDate::date() receives a timestamp
- add_xref.php, edit_xref.php: redirect to getEditUrl() after save/cancel
- list_xref.tpl: use getXrefRecordTemplate() instead of hardcoded liberty path
