refactor(chains): rename primitives to signing components

Replace Primitive* types and registry APIs with SigningComponent* across chain-core and sdk.

Migrate lattice signers/context to resolveSigningComponent with EXTERNAL.SIGNING fallback to preserve DeviceContext compatibility.

Rename primitive-focused modules/tests and keep transactional plugin register/unregister cleanup for plugin-owned signing components.
