Convert the remaining pages onto the Pressing Plant system: PageHead
component, shared list-row / toggle / small+ghost button / tracklist classes,
and page wrappers trimmed now that the shell provides masthead + nav. All
logic and test hooks (aria-labels, button text) preserved. Verified in the
real app across both themes (Playwright): artists/discover/wanted/discography
render cohesively with real data.
