Timesheet reporting views for projects, tasks, and employees now open with a weekly grid by default. This makes time review more consistent and easier for managers who typically track work on a weekly basis.

This commit sets `week` as `grid_range` in the grid view of `Timesheets by Project`,
`Timesheets by Task` and `Timesheets by Employee`.

The record is read directly in sudo, the prefetch is in the sudo
environment. When reading the other information there is no longer any
need to make a request.

This update reorganizes how activity information is managed in the Mail app, keeping related logic closer to the activity view. It should make the code easier to maintain without changing how users interact with activities.
