fix: parameterize AddPost fallback UPDATE, guard args indexing

Browse Source 
Posts.hasImage/DateModified fallback update built its WHERE clause via
raw string concatenation of blogName/postID, unlike every other query
in this method — a blog name containing a single quote would break or
inject into the query. Switch it to parameters.

--parse, --blogsO, and --bop indexed args[1..3] before checking
args.Length, so a missing argument threw IndexOutOfRangeException
instead of hitting the intended usage message.
