Add Filament admin panel and creative public portfolio site

Adds a Filament admin (Profile settings page plus CRUD resources for
Education, Experience, Projects, and Posts) backing a public-facing
personal site: hero/about/timeline home page, project showcase, and
blog, styled with a dark editorial theme (Fraunces + Instrument Sans).
