Add PHU AI branded hero artwork and social preview metadata

[Copilot]

The dashboard did not reflect the supplied PHU AI key art or tagline. This updates the landing experience to surface that branding directly in the app and ensures shared links use a local preview image instead of an external attachment.

• Dashboard hero

  • Adds a new top-of-dashboard hero block with the supplied PHU AI visual language
  • Introduces the tagline “Every evolution begins with a spark.”
  • Adds hero CTAs that route into existing app tabs instead of introducing new flows

• Local branding assets

  • Adds a self-contained vector artwork asset for in-app rendering
  • Adds a rasterized PNG companion for social-card compatibility

• Metadata / share preview

  • Updates favicon to use the local PHU AI artwork
  • Adds description, og:*, and twitter:* metadata
  • Points social preview tags at the local PNG so previews do not depend on GitHub attachment URLs

• Navigation reuse

  • Extracts tab switching into a shared path so both header nav and hero buttons use the same behavior
