fix: Android JDK 21, landing-at-root + app-at-/app, version bump

Android build failed with "invalid source release: 21" because Capacitor 7
requires JDK 21 (workflow had JDK 17). Bumped Android setup-java to 21.

Landing page got wiped on every deploy because deploy-web.yml used
force_orphan: true, which orphan-pushes the gh-pages branch and erases
the /landing folder that deploy-pages.yml had placed there. Merged both
workflows into one (Deploy Site - Landing + Web App) that:
  - Builds the web app with vite build --mode web
  - Assembles a site/ dir: landing at root, dist at /app
  - Single force_orphan push, no more race / overwrite
Deleted the now-redundant deploy-pages.yml.

Updated landing CTAs to point at ./app/ instead of GitHub releases:
  - Nav: "Download" becomes "Launch Web App"
  - Hero: primary "Launch Web App", secondary "Download Desktop / Mobile"

Bumped package.json 3.1.0 to 3.1.1 so artifact filenames match the
release tag.
