Revert "kcms/baloo: use frameless style for InlineMessages in header"
requested to merge ngraham/plasma-desktop:revert-frameless-header-inline-message-for-baloo-kcm into Plasma/6.1
This reverts commit 3e5964c5.
This commit went in too early, as it depends on a change in Frameworks 6.3 but Plasma 6.1 can't depend on Frameworks 6.3 yet. Revert it here and keep it in master, so it lands in Plasma 6.2 with the rest of them.
