=== Description ===
Update TKUI to remove or disable experiment creation and editing functionality in order to ensure experiment data is displayed as read-only and reflects GrowthBook configuration.
Relevant files:
Backend:
- `routes/experiments.js`
- `controller/instrumentController.js`
- `service/instrumentService.js`
Frontend:
- `frontend/src/`... relevant experiment create/update views and routes
New files:
likely none; mostly UI and route/permission changes
Currently `routes/experiments.js` still wires POST /experiments and PUT /experiment/:slug through instrumentController -- this eventually needs to become disabled/read-only
=== Acceptance Criteria ===
[] Experiment create/update actions in TKUI are disabled.
[] Backend no longer accepts experiment authoring changes in GrowthBook-only mode.
[] UI shows experiment config in read-only form.
[] Existing instrument authoring remains unaffected unless intentionally changed.
[] UI/integration tests cover read-only behavior.
