Summary by cubic

Merges the staged timesheet, task, and project board changes into develop.

Timesheets

• Approvals and view pages are rebuilt as aligned grid layouts; approvals gains a status filter with counts and an "All" option.
• The view page can approve and deny timesheets from the page itself, and the edit-time-log modal's overlap warning is now a callout inside the form.

Tasks and project board

• Subtasks can be added from the task page with the parent locked, and task rows now show priority and assignees.
• Dragging a card on the project board scrolls horizontally and marks the column it will land in.
• Images in rich-text descriptions stay within their column.
