BridgeJS: Fix static property call expression for namespaced classes

Static properties on `@JS(namespace:)` classes used
`property.callName()` to build the Swift call expression. That method
consults `property.staticContext`, which is stored as
`.className(abiName)` (e.g. `__Swift_Foundation_UUID`), and emits
`\(abiName).\(propertyName)`. The ABI-mangled name is not a valid Swift
identifier so the generated thunk failed to compile.

Static methods were unaffected because `renderSingleExportedMethod`
passes `klass.swiftCallName` directly.

Fix `PropertyRenderingContext.callName(for:)` for the `.classStatic`
case to bypass `property.callName()` and build the expression directly
from `klass.swiftCallName`. This preserves the ABI symbol name
(which still comes through `context.className` → `klass.abiName` →
`property.getterAbiName(className:)`) while producing a valid Swift
call expression in the thunk body.

Also remove the now-unnecessary comment from `prelude.mjs` that
described what the test was checking (the assertion itself is
self-explanatory).
