tdf#77111 cui,sw: fix page number offset on paragraph dialog "Text Flow"

Commit c2ccd20c0fd92bddfff76447754541705e3eb8f3 introduced 0 as a valid
value for page number offset in sw core.

Unfortunately the paragraph dialog was not changed then; previously
page number 0 would do automatic numbering, but since then 0 was set as
the offset, and once you have a 0 offset there's no easy way to remove
it, you have to remove the whole page break.

* change the label before the text number edit widget to a checkbox
that disables the edit widget

* keep the id "labelPageNum" so that translations still work

* adapt SfxToSwPageDescAttr so it can not just set but also clear the
page number

* set initial value to 1; 0 is a really bad default since we can't
export it to ODF (see tdf#91306)
