feat: fix per-view settings persistence and add recent weather cities

Per-view settings (cellDuration, showSomeday, etc.) now persist across
page reloads by using a ref to avoid stale closure bugs in saveViewSetting
and removing global state pollution from per-view onChange handlers.
Weather display fixed to use effectiveWeatherEnabled for fetch/render.
Added weatherRecentCities (max 8) as quick-switch pill buttons.
Kanban checkboxes now respect the showTaskCheckboxes per-view setting.
