feat: configurable tab labels and search nouns from plugin metadata

Script plugins can now declare tab_label and search_noun in their
plugin.toml [[providers]] section. These flow through the Provider
trait, IPC ProviderDesc, and into the UI via provider_meta::resolve().
Unknown plugins auto-generate labels from type_id instead of showing
a generic "Plugin" label.
