♻️ Implement website design feedback

[Jord-Gui]

Refactor website design based on feedback from @bradystroud and @JackDevAU. This includes:

• Moved SSW Dory logo to the left of the page
• Change the "Automatically send out reminder emails" screenshot to refer to an actual user
• Fix the broken svg format screenshot
• Add link to ssw.com.au in footer
• Reduce h1 tags to one
• Add Open Graph metadata tags
