Add password-based registration + login alongside existing magic links. New /register and updated /login with tabs (password default, magic link as alternative). Bun.password.hash/verify for bcrypt. Auto-login on register. Landing page CTAs point to /register. Add projects.artist field for grouping projects by artist in sidebar. Sidebar shows collapsible artist sections (▸ Anna Berger) with project counts, "Ohne Zuordnung" for ungrouped projects. Search filters across artist names. New/edit project forms include artist field. Fix timezone bug: set postgres connection timezone to UTC so magic link expiry works correctly in CEST and other non-UTC timezones.
