chore: remove dead E2E infrastructure per CTO decision (aff63c4)

E2E approach is dead — removed from main in aff63c4. These files
re-introduced broken E2E infrastructure that will fail CI on every
uat→main promotion.

Removing:
- .github/workflows/e2e.yaml
- deployment/e2e-ci-runner-rbac.yaml
- scripts/deploy-e2e-headlamp.sh
- scripts/teardown-e2e-headlamp.sh
