Rebrand website to match dashboard

[fstoqnov-iohk]

Here is the Leios redesign work done as per this ticket request - https://input-output.atlassian.net/browse/MK-8266

I have also slightly adjusted the styling of the non-homepage pages to fit the look and feel of the rest of the new design of the homepage

Let me know how you wish to proceed with this release

Changes technically look good, except some cleanup and the likely too big social preview image.

I'm a bit worries about the number of theme/ modifications needed. Do we really need all of them? I understand you probably instantiated the default theme and modified it when developing this. Can you please double-check what is needed and do cleanup where possible?

In general: remove assets and components that are superseded by the new design.

Thanks!

Thanks for the cleanup. I needed to fix the svgs to load correctly and also not get clipped. I have also dropped the link to documentation buttons as agreed between olga and me. See last few commits for context.

In the Figma, there a 3 images on the hompage for:

1. Scalable
2. Secure
3. Flexible

We want to change the 3rd image to "Decentralized"

The image should represent diverse SPO nodes (maybe cubes) disrtributed around the globe and all interconnected.
