fix: macros were not being saved

macros were being discarded as unknown blocks when they should've been
saved as a block with a known type.  Introduced a new type number as
macros don't have most of the attributes that blocks or pages do.
Features like collapsible queries now work in db graphs. Also removed
an outdated reference that assumed macro was a page (which it no longer
is)
