fix(ui): improve endpoints ordering

[bodinsamuel]

Changes

• Improve endpoints ordering
  We were only pushing items up if the comparison was directly different, so when we compared POST to DELETE, POST was not pushed up.

can we do?

const METHOD_PRIORITY = {
  'GET': 1,
  'POST': 2,
  'PUT': 3,
  'PATCH': 4,
  'DELETE': 5
};
return METHOD_PRIORITY[a.endpoint.method] - METHOD_PRIORITY[b.endpoint.method];

unrelated to this PR but I am not sure why we have 2 .sort chained one after each other.
Also this sorting logic is becoming quite complex and I feel could be refactored like:

            groups.push({ name: group[0],
                flows: group[1].sort((a, b) => {
    
                    const comparePaths = (pathA, pathB) => {
                        const countPathSegments = (path) => (path.match(/\//g) || []).length;
                        const lenA = countPathSegments(pathA);
                        const lenB = countPathSegments(pathB);
                        if (lenA !== lenB) {
                            return lenA - lenB;
                        }
                        return pathA.localeCompare(pathB);
                    };

                    const compareMethods = (methodA, methodB) => { ... };

                    const pathComparison = comparePaths(a.endpoint.path, b.endpoint.path);

                    if (pathComparison !== 0) {
                        return pathComparison;
                    }

                    return compareMethods(a.endpoint.method, b.endpoint.method);
                })
            });
