The web UI is now mounted at /web/ (previously /ui/) — cmd/server/main.go
wraps web.Server.Handler with http.StripPrefix("/web", ...), so
internal/web's own routes stay unprefixed (/, /login, /logout,
/shares/..., /static/...) and only the outer mux adds the prefix. All
templates, redirects, and cookie paths updated accordingly. The root '/'
route reverts to the original unauthenticated welcome page (linking to
/web/), and /cal/, /card/, /files/ are unaffected.
Also gitignore the bin/ build output directory.
