fix(ui): make the settings dialog movable

[soloturn]

Closes #468.

The settings dialog used StageStyle.UNDECORATED - no native title bar means the OS window manager has nothing to let the user drag, so the window is stuck wherever it opens. On a multi-monitor setup that's always the primary display, exactly as reported.

The main launcher window already uses StageStyle.DECORATED, so this brings the settings dialog in line with that (using UTILITY instead - a thinner title bar without minimize/maximize, appropriate for a modal dialog rather than a top-level window). Also set the window title via the existing (already-translated, previously unused) settings_title label key, since UTILITY/DECORATED need a title to not show a blank bar.

No changes to the close/save/cancel behavior - those already close via getWindow().hide() on the button's own scene, independent of stage style.

Test plan:

• ./gradlew build succeeds

Merge Risk: ⚪ Minimal · up to 7a075

This localized UI change makes the settings dialog movable and gives it a translated title without changing close, save, or cancel behavior; no actionable merge-blocking risk remains beyond normal checks and review.

Poem

A rabbit sees the title glow
The settings window moves just so
A native bar crowns the view
With words translated, crisp and true
Hop, hop—the dialog now can go
