Remove the single-caller legacy `base/content-dialog` wrapper and
migrate `AppInfoDetailPanel` to composable `DialogBackdrop`/`DialogPopup`
exports from `base/ui/dialog`, preserving left-side drawer semantics
and slide animation.
- Add `DialogBackdrop` and `DialogPopup` to `base/ui/dialog` so callers
can compose non-centered overlays without bypassing the abstraction
- Refactor `DialogContent` to reuse the new primitives internally
- Replace `@remixicon/react` imports with `i-ri-*` icon classes
- Fix `cloneElement` in `app-operations` to merge className via `cn()`
instead of replacing it (broke CSS-class icons)
- Replace invalid `overflow-wrap-anywhere` with `wrap-anywhere`
- Delete `base/content-dialog/` (component, stories, tests)
- Prune orphaned eslint-suppressions
