feat: HA/Google edit, full-page event detail, KW+zigzag divider, HSV picker, splash
- Home Assistant & Google events now editable/deletable (server PUT/DELETE
endpoints wired; saveEvent had no HA/Google update branch -> created dupes)
- Event detail is now a full screen (Scaffold) instead of a bottom sheet:
long notes scroll, action buttons no longer hidden behind the system nav bar;
distinct calendar vs notes icons
- Month view: calendar-week number on Mondays, month-boundary divider with
zigzag step (month_divider_color), month label in month_label_color,
text/line contrast applied
- Compact top bar with smaller title; prev/next chevrons present in month view
and scroll one month at a time
- Real HSV colour picker (SV field + hue slider + hex) for primary, accent,
today, month-divider and month-label colours
- Black status/navigation bars; portrait-locked; crisp custom splash with app
name, high-res icon and © Scarriffle
