chore(desktop): drop the embedded catalog picker's leftovers

The card catalog replaced the iframed docs-site picker on Capabilities ->
Plugins. Remove what only that pane used: CATALOG_PICKER_URL and the
catalogTitle / catalogBrowse / catalogHide / catalogHint strings (5
locales, types, overlay gaps, keys manifest). The plugins.json feed, the
hermes://plugin/install deep link and catalog installs are unchanged.
