fix(plugins): list the marketplace and install plugins from the welcome screen

The Plugins page on the welcome screen showed "[object Object]" and "There is no online plugin repository" (even with a marketplace configured), and Install did nothing. - Marketplace and package commands (index, download, unpack, install preview, theme import) only touch the IDE's own state and are allowed without a trusted project. - Installing, uninstalling, enabling and granting plugins are allowed where no project is open; an untrusted project still blocks them. - Errors rejected as plain backend error objects show their message, and a marketplace that couldn't be read shows the error instead of the "no online repository" note.
