test(connector-id): migrate fixtures and assertions to pi-mono ids

Replaces legacy adapter ids (codex_local / claude_local / gemini_local /
claude_compatible) across ~42 test files with pi-mono equivalents:
- codex_local → openai-codex
- claude_local → claude-pro
- gemini_local → gemini-cli
- claude_compatible → anthropic

Hand-rewrites where fixture semantics changed:
- connector-matching: TASK_TYPE_PREFERENCE ordering rebased (claude-pro
  first for code/content/management; google first for research)
- connector-model-policy: getModels(provider) from pi-ai instead of the
  deleted adapter.module.models array
- session-management + edge-case-session: adapter exemption removed;
  rotation now uniform under pi-mono
- ipc-core-admin-handlers: CSV compat model replaced with pi-ai anthropic
- connectors.spec: lookup by openai-codex id (catalog now starts with claude-pro)
- onboarding-model-pool: listProviderModels(provider) helper; label text
  changed to "ChatGPT Plus/Pro (Codex)"
- database integration: added vault insecure-fallback env + electron mock
- command-paths: uses new @main/connector-helpers normalizeCommandValue
- pi-mono-migrations: added `as string` casts for 3 negative-existence
  assertions verifying legacy ids were removed

Drops:
- pnpm-workspace.yaml packages: [] (was "packages/*"; directory empty)
- obsolete CONNECTOR_STRENGTHS import; .module.models probing

Verification:
- pnpm typecheck → 0 errors
- pnpm lint → 0 errors / 0 warnings
- pnpm build:verify → 0 errors / 0 warnings
- pnpm test:unit → 508/508 pass
- pnpm test:integration → 96/96 pass
- All 6 adapter hard gates pass (NOT FOUND / 0 matches / empty)
- pi-ai / pi-agent-core / pi-coding-agent all resolved @0.67.6
