fix(codex-config): close fix-round-1 parity gaps against CcConfig

Isolate the codex-CLI-backed reads (mcp/plugins/marketplaces) from the
file-backed ones in fetchAll via two independent Promise.all groups, so a
missing `codex` binary degrades only the mcp/plugins tabs instead of
leaving the whole panel stuck on skeletons. Generalize EditorModal's
nameless-type detection behind a `namelessTypes` prop (defaulting to
Claude's own ["memory"]) so Codex's config.toml can be created without a
name. Port BackupsModal, disable the plugin/mcp Remove button when no
stable identifier resolved, hide the inert search box on memory/config,
drop a redundant empty state, and reword the delete-dialog copy to be
tool-neutral.
