[pbs-devel] [PATCH proxmox-backup 7/7] ui: Dashboard/TaskSummary: show task overlay when clicking on a count

[Dominik Csapak <d.csapak@proxmox.com>]

when clicking on a count in the summary, a small task overlay now pops
up that shows those tasks. this way, the user has an easy way
of seeing which tasks failed exactly

if wanted or necessary, i could implement the grid overlay in its own
file, but it is 'special' enough that we probably will only use it here
(it is different enough from the 'running' tasks grid, that i did
not try to use that)
