feat: base UI shell with themes, auth pages, profile, and role navigation (phase 4)

- embedded Go templates + vanilla ES-module JS + hand-written CSS, no build step
- exact §10 beige light / dark design tokens, square edges (radius 2px),
  system font stack, visible focus rings
- theme toggle persisted to localStorage and the user profile
- login/register/change-password pages wired to the auth API
- profile page: avatar upload (image-sniffed, old file cleanup), bio,
  contacts, arbitrary extra key/value fields, optimistic-concurrency 409
- role-based top navigation with placeholders for later-phase areas
- GET /files/{id} with scope-based access (session) or signed token (§5.1)
- security headers incl. CSP without unsafe-inline scripts
