fix(ci): drop invalid SWA input, gate deploy on token via env guard

Azure/static-web-apps-deploy@v1 has no `skip_deploy_on_missing_secrets`
input (confirmed against its action.yml), so passing it did nothing but
emit an "Unexpected input(s)" warning — the intended "skip green on
Dependabot PRs" behaviour was never actually in effect.

Replace it with the documented mechanism: surface the deploy token as a
job-level env var and gate the deploy/close step with `if: env.DEPLOY_TOKEN
!= ''` (secrets cannot be referenced directly in an `if:`). On Dependabot
PRs the token is absent, so the step skips and the job stays green; real
deploys on main and internal PRs still run. Applied to both jobs.
