## Summary
- retire the tenant panel runtime and converge operator routing on the workspace-first admin shell
- update tenant, operations, and required-permissions navigation helpers to use canonical workspace-scoped URLs
- repair the focused feature coverage, add the Spec 280 browser smoke, and record the implementation close-out in the requirements checklist
## Validation
- `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/WorkspaceFoundation tests/Feature/Workspaces tests/Feature/ManagedEnvironment tests/Feature/RequiredPermissions tests/Feature/Operations tests/Feature/MonitoringOperationsTest.php`
- `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Browser/Spec280WorkspaceTenancyEnvironmentRoutingSmokeTest.php`
- `cd apps/platform && ./vendor/bin/sail bin pint --dirty --format agent`
## Note
- `origin/platform` is not present on the remote; `platform-dev` is the clean base branch that limits this PR to the Spec 280 prep commit plus the implementation commit.
