Simplify sidebar workspace status indicator

Hide the kind icon entirely when a workspace is idle, and give the
attention state a standalone dot instead of overlaying it on the icon.
Restructure the row into an icon column plus a content column so the
subtitle and PR badge align under the title without hardcoded indents.
