Passkey energy v0

[depatchedmode]

Summary

I've updated the copy, styling and branding to prepare for the Passkey.Energy launch, with links back to the odd.dev website. Related issue is open to map the domain, here: https://github.com/fission-codes/infrastructure/issues/227

Align with our Passkey.Energy stickers in preparation for handing out at DWeb camp and raising awareness about the path to enabling passkeys as an encryption factor.

@hugomrdias Made the requested changes. Updated logo.svg and logo-borderless.svg with just the standalone Passkey.Energy symbol (w/o the wordmark). You can generate PWA icons from that. Let me know if you need anything else.
