fix(eng-10262): added correct encoding of next query parameter

[ihorsokhanexoft]

https://openscience.atlassian.net/browse/ENG-10262

Purpose

For LOCAL env only:

A new next query parameter must be the first one to be encrypted and then encrypted one more time with service query parameter together.
So everything after localhost:8080/login?service= is encrypted and the next query param with its value is encrypted twice.

Also in the middle of the url, we should use ? instead of & (%3F - encoded, between login and next words) so that the next parameter belongs to service, not the main request

http://192.168.168.167:8080/login?service=http%3A%2F%2Flocalhost%3A5000%2Flogin%3Fnext%3Dhttp%253A%252F%252Flocalhost%253A4200%252F

And CAS should handle login, not angular, so we replace 4200 port in service query parameter by 5000

Suggested change

	export const localUrlParam = (params: { service: string; next?: string }) => {
	const { service, next } = params;
	// encode "next" separately because it must be encoded twice
	const encodedNext = next ? encodeURIComponent(next) : undefined;
	const valueAfterService = encodedNext ? `${service}?next=${encodedNext}` : service;
	return `service=${encodeURIComponent(valueAfterService)}`;
	};
	export const localUrlParam = (params: { service: string; next?: string }): string => {
	const { service, next } = params;
	if (!next) {
	return `service=${encodeURIComponent(service)}`;
	}
	const encodedNext = encodeURIComponent(next);
	const valueAfterService = `${service}?next=${encodedNext}`;
	return `service=${encodeURIComponent(valueAfterService)}`;
	};
