feat: Expose test tags as resource IDs for UI testing

This commit introduces a `Modifier.exposeTestTagsAsResourceId()` extension to make Compose `testTag` attributes available as resource IDs in UI tests. This simplifies element lookup for automation frameworks.

The new modifier has been applied to the root `Surface` in `EudiComponentActivity` and the `ModalBottomSheet` in `WrapModalBottomSheet` to enable this functionality at the top level of the UI hierarchy.
