Current topic: "Aligning Tests with UI and Hardening Interactions"
Topic summary: I am updating the regression tests to align with the UI changes and improve robustness. Specifically, I'll add a click to dismiss the new "Success" dialog in `rS02` and `rA06`. I'll also add `performScrollTo()` to the attachment removal button in `rA05` to handle off-screen elements. Finally, I'll update `killAndRelaunch` in `RegressionHelpers.kt` to wait for the `SCREEN_TITLE` tag instead of just text, which should be more reliable in the `LargeTopAppBar` context. These changes should resolve the remaining 5 failures.

Strategic Intent: I will update the regression tests to accommodate the new success dialogs and improve interaction reliability by adding explicit scrolls and tag-based waits.
