Adjust subtask count to exclude empty or blank entries from the total displayed in the task summary.

Description:

Currently, the subtask count includes empty entries or blank subtasks, which inaccurately inflates the total displayed in the task summary. Please adjust the count to only include non-empty subtasks to reflect the actual number.

Acceptance Criteria:

• Subtask total only counts non-empty subtasks.

• Displayed total accurately represents populated subtasks only.
