HYPERFLEET-1024 - chore: switch spectral lint to stoplightio/spectral-action

Replace manual npx spectral invocation with stoplightio/spectral-action@v0.8.13.
The action bundles its own Spectral binary, avoiding Node.js version
compatibility issues with npx. Remove @stoplight/spectral-cli devDependency
as it is no longer needed. Update TypeSpec compiler to @1.11 in both workflows.
