Registry UI: on login page, add support for redirects

[severinbeauvais]

(This was previously #10866, but it got hijacked for other work.)

Description

The BC Registries login page should support a URL parameter to redirect to after successful login. If the redirect URL is not specified then just go to the BC Registries dashboard after login. For example:

1. ensure you are not logged in
2. go to an entity's dashboard (eg, https://dev.bcregistry.ca/business/https://dev.bcregistry.ca/business/CP1002494)
3. you are redirected to BC Registries login page
4. login (BCREG0020)
5. you are redirected back to the entity's dashboard

** See use cases in Test Notes below. **

@forgeuxGH5 @yuisotozaki This ticket is ready for UX Assurance. The code has been deployed to Dev and Test environments.

Note that you may have to refresh once, initially, to get the latest version. The DevTools Console should display bc-registry v1.0.13.
