Add tiled homepage; rename Business→Businesses; link footer copyright

- Home page (home.html) at / shows the sidebar sections as tiles; reachable by
  clicking the 'SimpleX Manager' brand in the sidebar (was redirecting to /users).
- Rename the category to 'Businesses' (route /businesses, tab/nav/_category),
  keeping the per-account bot_type 'business'. Fix profile back-link label.
- Footer: link 'Bournemouth Technology Ltd' -> bournemouthtechnology.co.uk and
  'SimpleX Network' -> simplex.chat.
