WSTEAM1-705: Links to posts on live page (SPIKE)

[Isabella-Mitchell]

Resolves JIRA [WSTEAM1-705]

Overall changes

Spike to explore Linking to Posts/ Linkable Key Points. Based on PS implementation. See the dropbox paper linked to the ticket.

Code changes

• Hard code in some test links
• Passes post param into 'getPageData' function
• Add 'scrollToLatest' hook which uses 'scroll-into-view' helper (doesn't work with links that end with #post)
• Render 'BackToLatest' link above selected post
• Use #post to direct user focus to the 'BackToLatest' link
• Hard code in stream 1st page link
• Add a Stream Provider (not sure I'm using this to it's full extent).
• Modify NextJs app set up so to connect to local BFF
• Add some hacky 'copyToClipboard'/ Share helpers.
