fix(parser): allow blank lines within a table block

Blank (whitespace-only) lines inside a table no longer split it into
separate blocks. They are buffered and discarded if more table rows
follow, enabling patterns like pre-filling a recurring meeting entry
with a blank line separating it from the rest of the day's entries.
