1. cellDuration indicator: compare against local `cellDuration` state
(not effectiveCellDuration which reads stale profile.cellDuration
since saveSetting bails early for DEVICE_SETTINGS_KEYS)
2. viewDays on mobile now uses orientation instead of fixed width:
portrait (h > w) → 1 day, landscape → 3 days, for ≤768px.
Applied consistently in useEffect, early profile load, and cookie
override blocks so the responsive value is never overridden by
the saved DB preference on mobile.
3. list-view day header on mobile: changed from sticky to
position:relative so it flows with content and never covers tasks
4. time/day column scroll sync: weekly-days-grid was overflow-y:auto
on mobile, creating an independent scroll container that drifted
from the time column. Changed to overflow-y:visible so only
time-grid-wrapper scrolls. Added touch-action:pan-y to day columns
so iOS handles pan immediately without waiting for JS.
