chore(elisp): clear byte-compile warnings (org-noter, calendar-sync, vc, dirvish, org-contacts)

Add declare-function/defvar declarations for lazily-loaded package symbols and reflow over-long docstrings so these modules compile cleanly standalone. org-contacts keeps the diary special vars (date/entry/original-date) declared function-locally rather than file-wide, so the lexical `entry` parameter is unaffected. No behavior change.
