iOS drawer: flat reorderable calendars, long-press menu, left-swipe close, header actions

Testing feedback:
- calendars are now one flat, drag-reorderable list (no per-source grouping);
  order is device-local (CalendarStore.calendarOrder, mirrors the web cal_order).
  Reordering is done via a 'Sort' toggle (native edit mode with drag handles).
- banish + reminder-mute moved from row swipe actions to a long-press context
  menu, which frees the horizontal swipe: swiping the drawer left closes it.
- the hamburger moved to the LEFT (drawer opens left); new device-local setting
  'Hide menu button' (open via edge-swipe only), not synced.
- the settings entry moved from the footer into the header as an icon, next to a
  restored manual-sync icon and the close button; the footer button is gone.
