UI: Auth Layer - Modified Login Account Flow

[cameron-eyds]

• [x] Configurations for authentication options
• [x] Pass params on navigation - through ALL pages
• Scoped to piece together the pieces of the account flow
• Implement playground flow and examples for auth flow
• (ie configurable login -> select/create -> affiliation/final redirect)
• e2e testing

Notes

• Check if currently authenticated with IDIR or BCEID: Need to handle this?
• ie logout or continue user forward if authenticated with BCSC
• Potential for global model driven by plugin: checking idp or terms of use etc
