feat(services): clone/move ops + owner-scoped registry credentials (C4)

Service lifecycle: POST /services/:id/clone duplicates config, volumes,
domains, access gates, builder settings, and variables (secret ciphertext
copied verbatim); POST /services/:id/move re-parents to another owned
project. Both enforce ownership, reject name conflicts, and audit.

Registries: CRUD at /registries — host-matched pull credentials for
prebuilt-image deploys, encrypted at rest via secrets pkg, never returned
(has_password flag). Empty password on update keeps the stored credential;
host normalized (scheme/case/trailing slash). Credentials thread through
BuildConfig → BuildRequest → pull auth config, used only for the pull.

Surfaces: CLI services clone|move + registries group, 7 MCP tools,
OpenAPI paths/schemas, frontend Lifecycle card (clone/move/delete) and
Settings registries section, llms.txt + CLI.md.
