The calendar picker was an AlertDialog holding a non-scrolling Column, so
accounts with many calendars overflowed the dialog's fixed height and the
entries past ~9 were unreachable (Codeberg #29).
Replace it with the app's FullScreenPicker (collapsing scaffold + scrollable
content), rendering calendars as connected GroupedRows grouped under their
owning account — the same grouping the visibility filter and calendar manager
use — with a colour chip per row and a check on the current selection.
