fix: pin SSH host key via known_hosts instead of StrictHostKeyChecking=no (#161)

- Add knownHosts *dagger.Secret parameter to Deployer(), DeployLinux(),
  DeployApk(), PublishWebsite(), BuildWebsite(), GenerateBuildHistory()
- Mount SSH_KNOWN_HOSTS secret at /root/.ssh/known_hosts (mode 0644) in
  both the Deployer container and the GenerateBuildHistory container
- Remove all -o StrictHostKeyChecking=no flags from ssh/scp/rsync calls
  in ci/main.go and scripts/generate_build_history.py
- Update Taskfile dagger tasks (deploy-linux, deploy-apk, publish-website)
  to require SSH_KNOWN_HOSTS and pass --known-hosts env:SSH_KNOWN_HOSTS
- Fix non-Dagger Taskfile tasks to write SSH_KNOWN_HOSTS to ~/.ssh/known_hosts
- Fix .forgejo/workflows/deploy.yml to pass SSH_KNOWN_HOSTS secret
- Fix .github/workflows/ci.yml SSH setup step to write known_hosts file
