Add add_person/add_business flows; tidy contact view/edit for type

- add_person.php + add_person.tpl: minimal form, auto-injects $00
- add_business.php + add_business.tpl: org name + $02+ type checkboxes
- menu_contact.tpl: replace generic edit link with Add Person / Add Business
- Contact.php: fix title overwrite (org no longer clobbers person name);
  fix null trim on organisation; fix $00 type xref stored correctly
- edit.php: isPerson flag; xref groups loaded; type list filtered $02+ for businesses
- edit.tpl: person/business field visibility; tabbed xref block at bottom of Details tab
- edit_type_header.tpl: value fixed to {$type.item}; $00/$01 filtered out
- display_contact.tpl: person/business field selection; note above addresses;
  no-addresses fallback removed; allow_edit=false on xref tabs
- display_type_header.tpl: heading Personal/Business Contact; $02+ types only
- contact_date_bar.tpl: remove Add crossref shortcut (now in edit tabs)
- view_xref_*_item.tpl: dates and edit actions gated on $xrefAllowEdit
