Problem

• On the studio logs:
  • the log list are paginated on client-side.
  • the preview files list is not paginated.
• On the entity lists, a silent PDF loading process runs without reason.
• Errors can happen when deleting and then filling in dates in editable task lists: My Tasks, entity tasks, ...
• Some npm dependencies are outdated

Solution

• Switch to server-side pagination for the log list
• Add server-side pagination for the preview files list.
• Fix the unwanted PDF loading in the background, due to a v-show.
• Fix the task start date and due date updates on the editable task lists. A Moment date was set instead of a string date.
• Bump npm dependencies.
