Applies the panel copy rules to the five builtin extensions. Tab,
page-title and command-palette labels go to sentence case (Cloud
servers, FTP server, Remote access, Status pages); display names stay
as extension names.
Walkthrough Studio: no period on short toasts, "Couldn't" errors, a
delete confirm that states the consequence, and four hardcoded strings
wrapped in t() (kicker, step eyebrow, default duration and action),
with Spanish for the new keys. 30 strings in all: Studio 16, cloud
provisioning 4, FTP 4, remote access 3, status 3.
Synced into frontend/src/plugins and the tracked live serverkit-status
manifest.
Visual authoring tool for walkthroughs: create and reorder steps, pick
highlighted UI targets, choose completion modes (route, signal, manual,
check), validate against the shared schema, preview in a live dock,
publish to the server library, and import/export JSON or copy an
extension contribution block. The Studio dogfoods the new system by
declaring its own getting-started walkthrough in its manifest.
