fix: make Reduced motion gate overlays, standardize the tab band, and polish fleet/snapshots (#1504)

* fix: address review feedback on motion, fleet band, and snapshots

- Reduced motion now also skips the animate-ui overlay open/close animations
  (dialog, sheet, popover, dropdown-menu) via a shared useReducedTransition that
  zeroes the transition when reduced motion is active; MotionConfig alone only
  neutralized transform/layout, leaving the opacity/blur fade.
- Fleet tab band: flatten the list's own pill band so the tabs sit in a single
  full-width band instead of a nested second band.
- Fleet Overview: label the node-update button "Node Update"; the add-node
  button becomes a ChartNetwork icon that opens Settings > Nodes (outline style,
  matching the node-update button) instead of the add-node modal.
- Blueprint deployments empty state: drive the serif headings from the theme
  heading-style token so Calm drops the italic.
- Snapshots: move the per-stack Restore onto the stack header row (right side),
  matching the ghost action style.

* feat: standardize the tab band on Security and add a tab hover state

- Apply the Fleet full-width tab band to the Security page (single band, the
  list's pill background flattened so the tabs sit directly in it).
- Add a hover highlight to tabs so the band reads as interactive, not flat;
  the active tab is unaffected.

* fix: drive reduced-motion transitions from the app setting, not the OS query

useReducedTransition called framer-motion's useReducedMotion(), which only
reflects the OS prefers-reduced-motion media query and ignores our MotionConfig
/ appearance toggle, so dialogs kept animating with the setting on. Read the
app's useReducedMotion selector instead. Verified: with the setting on, the
dialog opacity snaps 0->1 in one frame; with it off, it ramps over the spring.

* feat: standardize stack-detail body text to text-xs and add a log expand toggle

- Bump the anatomy panel body text (rows, field values, warnings) and the
  structured log lines from 10/11/12px to text-xs (12px), leaving the uppercase
  kicker labels and the log level/source badges as-is.
- Add an expand control next to the log download button that collapses the
  Command Center so the logs pane fills the left column; toggles back to restore.
