Fix task selection

[NicoPennec]

Problem

• Shift-clicking on a second task only kept the two endpoints in the task selection; every task in between fell into the "empty cells" group of the task panel instead.
• The entity progress count could crash when a row referenced a task or status no longer present in the project.
• Some npm dependencies are outdated.

Solution

• Restore the shift-click range so every task in the span gets selected.
• Ignore unknown tasks and statuses when computing the entity progress count.
• Bump npm dependencies.
