before this commit, The Kanban view for project tasks includes a subtask button,
a remaining hour timer, an activity button, and assignees in its lower section.
However, when the task has subtasks and timesheet entries, these buttons appear
in the Kanban view, causing the view to lose its structure somewhat.
This commit includes reducing the right margin of the activity button and
remaining hours to provide enough space for other elements in the kanban view.
Additionally, the Lock Icon for private tasks has been given a left margin to
separate it from the activity button
