feat: use consistent theming across the better suite

[LovelessCodes]

I have:

• Re-purposed the theming from Better Auth, to make the themes stay consistent across the Better Suite.
• Tried to come close to the Better Auth icon with the new Better Fetch icon.
• Fixed small mistakes that I've found around the Documentation
• Upgraded all dependencies

Hey, thanks for the PR! This looks like a lot of work, so thanks again. We need to polish a few things and will hopefully merge it in the coming week.

@Bekacru do you prefer this UI for docs? Happy to help polish it up if you do
