niri: working minimize via declared stash workspace

Mod+M referenced an undeclared 'minimized' workspace, so it silently did
nothing. Declare it, add focus=false so focus does not follow the window
into the stash, and point Mod+Shift+M at the restore picker.

niri pins declared named workspaces to index 1 and will not move them, so
Mod+1..9 are offset by one.
