docs: drop --license-file from install command (configure in setup wizard)

The installer was never required to take a .lic file — install.sh has no
--license-file flag, only --license-pubkey for embedding the Ed25519
verifier key. The licence is collected in the setup wizard step after
the server is reachable on :8082.

- Install command becomes the bare one-liner.
- Setup wizard adds the licence-upload step.
- Optional-flags table drops the non-existent --license-file row and
  surfaces the real --license-pubkey flag instead.
- Host-bound licence section points at the wizard / admin UI for
  uploading the .lic, not "re-run the installer".
