Two useful Planning search filters have been restored: one to find shifts for employees on time off and another to find published shifts that were later edited and may need resending. This helps planning users quickly identify schedule conflicts and updates that require follow-up.

This commit re-introduces two filters in the planning search view
that were removed after version saas-15.3
The first filter ("Employees on Time Off") shows the shifts of the
employees that have taken time off. The second filter ("To Resend")
shows shifts which have been edited after being published.

Both these filters should make it easier for users to navigate the
shifts in the planning app.
