refactor(lanes): compact the lane strip tile and the lane-detail header

The Workspace lane panel spent four rows saying what fits in two.

Strip tile: the stage badges move onto the id row and the progress bar
and percent go away — the detail panel's pipeline map right below shows
the same progress with the stage names attached.

Lane detail: the pipeline picker, stage badges, feature picker, router
select and the remove button merge into the single header row instead of
a second row under it, and the pipeline's name is no longer interpolated
into `laneHeader` — the picker beside it already says it. The git block
collapses from four lines to one and drops the cwd, which the header
above it already spells out.

The router select is relabelled Model, moves out of LaneCard into that
header row (`LaneRouterRow` is now exported), and reports its apply
outcome as a ✓/⚠ marker with the message in a tooltip rather than a
wrapped sentence that pushes every row below it down.

Drops the tracker / dev QC / CI wait badge row and everything feeding it
(`useLaneIntegrations`, `api.lanes.integration`, the `integrations.*`
strings): two of the three toggles have no consumer at all, and a badge
reporting a toggle nothing acts on costs a row of height to say nothing.
`agenthub lanes integration` and the API route are untouched.
