refactor(connectors): remove adapter module references from services

Drops every `definition.module.*` call and legacy id hardcode (claude_local,
codex_local, gemini_local, claude_compat_*) from the connector services.
Health checks now evaluate stored credentials against the declarative auth
descriptor, model policy reads provider models via pi-ai, matching keys off
provider ids, and hire-hook logs activity without invoking an adapter hook.
Introduces a local normalizeCommandValue helper to replace the deleted
@agentcompany/adapter-utils/server-utils import.
