feat(fleet): add node management actions to Fleet Overview (#1064)

* refactor(nodes): extract node create/edit/delete modals into useNodeActions hook

Pulls the inline Add/Edit/Delete/Pilot-enrollment modal stack out of
NodeManager.tsx and into a reusable useNodeActions() hook in
components/nodes/. Settings continues to consume the same modals via
this hook, with an onTestResult callback used by Settings to render the
existing connection-detail panel after a successful test.

The hook also extends the auto-test-on-save behavior so that saving a
proxy-mode remote node from the Edit dialog re-runs the connection test
when the API URL or token has actually changed (skipped when only name
or compose dir was edited).

* feat(fleet): surface Add/Edit/Delete node actions on Fleet Overview

Adds an admin-only Add node button to the right of Refresh on the Fleet
header, opening the same Add Node dialog used by Settings. Each node
card's three-dot menu now exposes Edit node and Delete node items
(routed through the shared useNodeActions hook) alongside the existing
Cordon item, so operators can manage node lifecycle without leaving the
Fleet page.

The card kebab is shown to admins regardless of tier; Cordon stays
Admiral-only. Delete is hidden on the local default node. After any
Add/Edit/Delete the Fleet overview refetches so the grid reflects the
change immediately.

* docs(fleet): document Add/Edit/Delete node actions on Fleet Overview

Updates the Action buttons table to cover the new Add node entry point
on the Fleet header, and adds a new Node actions menu section
describing the per-card Edit/Delete/Cordon items, their tier and
permission gating, and the auto connection test that fires after
saving a proxy-mode remote.
