fix(window,onboarding): enforce min window size; add relaunch from welcome check

- Narrow-window layout breakage: the borderless window (decorations:false) was
  not getting the OS WM_GETMINMAXINFO clamp, so live resizing dragged it below
  the 900px design width and triggered the broken <=860 fallback layout. Assert
  the minimum explicitly via set_min_size after the decorations are finalized so
  the OS clamps interactive resizes (config minWidth alone wasn't honored for the
  borderless window). Keeps the startup restored-size clamp as defense.
- Onboarding: the welcome 'running as administrator' check showed red with no
  remedy. Added an inline 'Restart as admin' action on that row (reuses the
  existing relaunch_as_admin command + handleRelaunch), so it can be fixed right
  from the welcome step. CheckRow gained an optional inline action slot.

 ### Fixed
+- **Window can no longer be resized below its usable size.** The borderless
+  window didn't get the OS minimum-size clamp, so dragging it narrow broke the
+  layout (the sidebar piled up full-width over the workspace). The 900×600
+  minimum is now enforced explicitly, so interactive resizes are clamped.
+- **Administrator check is fixable from the welcome step.** The first onboarding
+  screen's "running as administrator" check now offers an inline "Restart as
+  admin" button when it's red, instead of just showing "not found".
 - **Onboarding admin check no longer contradicts itself.** The "administrator
   rights" step claimed "already running as administrator" whenever the
   run-as-admin autostart task existed, even when the current session was not
