feat: wire all remaining API endpoints

- src/api/keys.ts: QK singleton for all 20+ query key patterns
- src/api/queries.ts: rewritten with QK + full mutation coverage:
  deleteWorkspace, updateWorkspace, scheduleDream,
  updatePeer, setPeerCard, searchPeer,
  deleteSession, updateSession, cloneSession, searchSession,
  createMessages, updateMessage,
  useSessionPeers, addPeersToSession, setSessionPeers,
  removePeersFromSession, setPeerConfig,
  createConclusion, deleteConclusion,
  useWebhooks, createWebhook, deleteWebhook, testWebhook,
  createKey

Shared primitives (just-in-time):
- ConfirmDialog: animated modal with keyboard/click-out dismiss
- FormModal: reusable modal shell
- InlineEditor: click-to-edit with commit/cancel

New surfaces:
- WorkspaceDetail: delete + schedule dream buttons
- ScheduleDreamModal: Zod-validated observer/session form
- WebhookManager: full CRUD + test emit (new /webhooks route)
- SessionDetail: delete, clone, session search, peer membership tab
- PeerDetail: editable peer card, semantic search tab
- ConclusionBrowser: create conclusion modal (Zod), per-row delete
