Select multiple tasks at once with keyboard and mouse in Grid View

### Description

I think it would be nice to have the ability to select multiple tasks (to clean or to set success or failed) at once in the Grid View by :
- Drawing a square with the mouse
- Click on a task, hold CTRL keyboard button, click a second task somewhere else -> two tasks selected
- Click on a task, hold SHIFT keyboard button, click a second task somewhere else -> a square a tasks selected, first task being at the upper left, the second at the lower right

### Use case/motivation

In some cases it would be really simpler and more efficient to select tasks this way in the grid view, instead of crafting a request in the Browse panel, iterating over the pages if several, etc.

No files or tests are named; start by locating the Grid View implementation and its existing task-selection and bulk-action entry points. Implement mouse-drag, Ctrl-click, and Shift-click selection, then verify that selected tasks can be cleaned or marked successful or failed and that the Browse panel remains unaffected.
