feat(fleet): reapply Compose configuration without a version update (#1716)

* feat(fleet): reapply Compose configuration without a version update

Add a distinct Fleet Reapply configuration path so Compose-managed nodes can recreate Sencho from the current on-disk project when already up to date, without pulling or rewriting the image reference.

* fix(fleet): confirm remote reapply and close concurrent tracker race

Require confirmation for remote compose reapply, and lock dispatch before the remote POST so a second request cannot overwrite a successful in-flight tracker.

* fix(ui): icon-only Reapply control so Up to date badge can breathe

Collapse the Node updates Reapply label into a tooltip so the status pill no longer wraps in the Status column.

* feat(editor): Save & Reapply self-stack via fleet compose reapply (#1726)

* feat(editor): Save & Reapply self-stack via fleet compose reapply

Eligible admins can apply on-disk Compose edits to Sencho's own stack from the editor using the same confirm, dispatch, and reconnect path as Fleet Node Updates.

* fix(editor): gate Save & Reapply label to self-stack only

Ordinary stacks were labeled Save & Reapply whenever the node was
reapply-eligible. Require the selected file to be the self-stack for the
toolbar label and diff confirm CTA.

* fix(ui): move compose diff action label helper out of dialog module

Keep ComposeDiffPreviewDialog component-only so react-refresh Fast Refresh
lint passes after the Save and reapply stacked merge.
