deploy: follow the landing rename and the exorecovery.ru domains

Bring deploy/ in line with the renamed app directories and with the
domains that are actually configured in the per-app .env files:

  fitnes           fitness.exorecovery.ru  3000  fitness-landing
  hotel            hotel.exorecovery.ru    3001  hotel-landing
  medcenterphysio  physio.exorecovery.ru   3002  physio-landing
  medcenterstart   start.exorecovery.ru    3003  start-landing

apps.conf, the README provisioning steps (directories, bare clones,
systemd units, the sudoers whitelist) and the exo-deploy usage line all
used the old medcenter / medcenterpersonal keys. The README table and
app.build.env.example still carried the *_DOMAIN placeholders.

Also refresh the tracked .env.example files: real VITE_SITE_URL values
instead of the old exodevices.ru sub-paths, and the amo lead tags that
match apps.conf.

Two lockfile fixes, both of which broke `npm ci` in exo-deploy:
- medcenterstart had no lockfile at all after package-lock.json and
  pnpm-lock.yaml were removed — restore package-lock.json and keep the
  pnpm one deleted, since the deploy path is npm;
- medcenterphysio/package-lock.json had lost "resolved" and "integrity"
  on 147 of its 236 entries — restore the complete file.

Verified: exo-render-nginx renders all four vhosts with no leftover
placeholders, and every package-lock.json agrees with its package.json.
