Settings dialogs were rendering text/spin/combo controls with Qt's
default light style, which clashed with the dark Omarchy theme — black
text on dark fills, white dropdown popups, rounded corners, and a
pill-style toggle that didn't match the native StyleToggleRow switch.
- Style.qml: collapse all radius tokens to 0 so Noctalia-compat widgets
inherit Omarchy's sharp-corner convention
- NToggle: rewrite to mirror the native 48x22 switch with accent fill
and a sliding 16x16 thumb
- NComboBox: skin contentItem, indicator, popup, and delegate so the
dropdown reads on dark themes
- NSpinBox: add a styled background, contentItem, and up/down indicators
- SettingsPanel calendar form + DynamicSettingsForm string field: drop
default TextField chrome for the same translucent foreground fill used
by WidgetCard, accent border on focus
