Lemenzo Clock v3.1 — premium responsive ecosystem redesign

- All activities keep content inside status-bar, display-cutout/camera-hole, navigation-bar safe insets on every edge.
- Header identity is a unified logo/title/privacy stack matching the Lemenzo ecosystem.
- Reduced border overload: surfaces carry hierarchy; blue is reserved for selected/primary states.
- Alarm cards have more breathing room and two-level actions; destructive Delete is separated.
- Repeat-day controls are modern selectable chips.
- Bottom navigation uses short localized labels to remain readable on Pixel 6a-class widths.
- Text-bearing controls prefer wrap-content + min-height rather than rigid fixed heights.
- Stopwatch primary action is full-width; secondary actions are separated.
- App branding is consistently Lemenzo Clock in launcher/application label.
- No alarm/timer/stopwatch/scheduling behavior was intentionally changed.
