fix: mark replies '?' after pagination yields no reply notes

Previously, the '?' marker only fired when page 1 returned empty notes.
Posts whose page 1 contained only likes/reblogs and whose page 2 came
back empty were never marked, so GetRepliesWithFilledText kept reselecting
them every iteration. Now mark after the pagination loop whenever
rowsUpdated==0 and at least one page returned 200 OK.

UpdateAllNoteReplyTextForPost now returns int so the caller can fold
the count into emptyReplyCount/rowsUpdated for accurate Done logging.
