fix: remove cultural identifiers from protocol titles for consistency

Cultural context remains in descriptions. Titles now uniformly use the
practice name without prefixing the culture, country, religion, or people.
e.g. 'Quaker Meeting for Worship' -> 'Meeting for Worship',
'Moroccan Jmaa Village Assembly' -> 'Jmaa Village Assembly',
'Aboriginal Yarning Circle' -> 'Yarning Circle'.
