Several website-related apps have had obsolete snippet configuration code removed after a prior website refactor made it unused. This is an internal cleanup that reduces maintenance overhead and should not change day-to-day website behavior for users.

* : website_appointment, website_helpdesk, website_knowledge, website_sale_renting, website_sale_subscription, website_studio

Following the website refactor [1], that code is not used anymore.

An unused shortcut in the Attendance Gantt view was removed because it was no longer referenced. This keeps the system configuration cleaner with no expected change for day-to-day users.

Remove unused action 'hr_attendance_gantt.action_open_gantt_create_view_form' since it is unused
