Improve entity list

[NicoPennec]

Problem

• Changing the department filter leaves previous tasks selected, even if they're no longer visible, causing inconsistent selection.
• When department filtering is active, the task selection uses an incorrect column index, leading to incorrect task selection.
• Row groups in entity lists compute a dynamic colspan using a visibleColumns computed property, which adds unnecessary complexity and overhead for a useless visual detail.
• Some npm dependencies are outdated.

Solution

• Clear selected tasks on department change.
• Fix the task selection logic when department filtering is enabled.
• Simplify the UI by removing unnecessary colspan from row groups in entity lists to avoid extra computations.
• Bump npm dependencies.
