Rework ReorderableColumn: the first cut measured each row, but grouped
cards have position-dependent padding, so slot heights varied and rows
snapped to the wrong places with no animation. Now rows are a fixed
uniform pitch, the target slot is the whole-pitches dragged, neighbours
slide aside with a spring, and the held row settles onto its slot before
the order commits. Add a lift (scale + shadow) on the held row and
cancel an in-flight settle if a new drag pre-empts it.
GroupedRow gains gapBelow so the reorderable list can own uniform
inter-row spacing.

Add a "Views" settings section that lets users pick which views the
top-bar quick-switch button cycles through and drag to reorder them,
plus an independent drag-to-reorder for the navigation drawer's view
list. Two separate configs: a view turned off in the quick-switch
cycle is still reachable from the drawer, which always lists every view.
- QuickSwitchConfig (order + enabled set) and a drawer order persisted
in SettingsPrefs (comma-joined enum names; "!" marks a disabled view).
Missing views append enabled and unknown names drop, so a future view
defaults into both lists.
- The pill cycles through the configured enabled views in order; the
drawer renders CalendarDrawer from the drawer order. Both threaded
from CalendarHost via CalendarHostViewModel.
- New ReorderableColumn: dependency-free, measurement-driven drag
reordering for the short grouped-card settings lists (no LazyColumn,
since settings are a single verticalScroll column). Commits one write
per gesture.
- The switch needs two targets, so the last two enabled views can't be
turned off.
