Fixed close button at Rewards custom tab Resolves https://github.com/brave/brave-browser/issues/48678 Chromium change probably: https://source.chromium.org/chromium/chromium/src/+/10303af4b9ba8510d05ca130a1545f0b303a2721 Pad snackbars in SettingsActivity when edge-to-edge SettingsActivity creates the SnackbarManager with a parent view of the android.R.id.content, which is an issue when drawing edge-to-edge, since that base content view will be drawing underneath the system bars. This change adds #getContentView() to ChromeBaseAppCompatActivity, which will return the proper content view for the activity.
