Is your feature request related to a problem? Please describe.
Tasks that are important or frequently accessed get buried under other items. Users currently have no way to keep priority tasks at the top, which makes it harder to focus on what matters most.

Describe the solution you'd like

• Introduce a “Pin Task” option for each task.
• When a task is pinned, it should stay fixed at the top of the task list (above all other tasks) until unpinned.
  Pinned tasks can be visually distinguished using a small icon.

Describe alternatives you’ve considered

• Using tags like priority or urgent, but this still doesn’t guarantee they stay at the top.
• Sorting tasks manually by editing them, which is inconvenient.

Additional context

• A simple pin/unpin toggle in the task card menu dialog itself would be enough.
• Pinned tasks should not interfere with filters they should appear at the top within the filtered view as well.
