chore(AI): addConfiguration flag cleanup (#10628)

This PR cleans up the addConfiguration flag. These changes were
automatically generated by AI and should be reviewed carefully.

Fixes #10627

## 🧹 AI Flag Cleanup Summary
This change removes the `addConfiguration` feature flag. The feature was
discarded, so this cleanup reverts the UI to its state before the
`addConfiguration` flag was introduced. The primary change is in the
strategy
menu, where the single "Add configuration" button is removed and the
original
"Use template," "Add strategy," and "More" buttons are restored.
### 🚮 Removed
- **Flag Definitions**
- `addConfiguration` flag from `experimental.ts` on the backend.
- `addConfiguration` flag from `uiConfig.ts` on the frontend.
- `addConfiguration: true` from the `server-dev.ts` config.
- **UI Components & Logic**
- The conditional rendering in `FeatureStrategyMenu.tsx` that showed an
"Add
configuration" button.
- The `useUiFlag('addConfiguration')` hook call and its import from
`FeatureStrategyMenu.tsx`.
### 🛠 Kept
- **UI Components & Logic**
- The original set of buttons in `FeatureStrategyMenu.tsx`: "Use
template",
"Add strategy", and a "More strategies" icon button. This was the code
path for
when the flag was disabled.
### 📝 Why
The `addConfiguration` feature flag was marked as completed with the
outcome
"discarded". This cleanup removes the flag and all related code,
preserving only
the intended code path, which is the UI behavior from before the flag
was
introduced.
