feat(pilot): Phase 6 — post-resolve templatize prompt + draft accept/reject

Closes the loop on the Phase 5 "Run now, templatize after resolve" path.
After a session resolves, drafts queued by the three-option dialog surface
as a modal that lets the engineer review the AI-proposed parameterization
and either save as a reusable team template or skip. A "don't ask again"
toggle writes to account_settings.preferences so the next resolve won't
pop the modal.

Backend:
- /api/v1/draft-templates:
  * GET — list account drafts (pending_only default true; pass false for
    audit view including accepted/rejected)
  * GET /{id} — single draft
  * POST /{id}/accept — promotes to a new script_templates row with
    source_session_id / source_user_id / source_ticket_ref populated
    (drives the Script Library "generated from CW #X · resolved by Y"
    provenance chip). Draft flips to status=accepted,
    promoted_template_id set, resolved_at stamped. 409 on re-accept /
    already-rejected. 400 on unknown category_id.
  * POST /{id}/reject — flips to status=rejected. 409 on re-reject.
- /api/v1/accounts/me/preferences (GET/PATCH) — thin wrapper over
  AccountSettings.get_setting/set_setting. PATCH merges keys into the
  JSONB column, preserving existing keys the client didn't touch.
  Used by the "Don't ask again for this team" checkbox
  (templatize_prompt_enabled=false) and, forward-looking, by
  cw_resolved_status_id / cw_escalated_status_id from Phase 4.
- 13 tests: list filter, accept with/without edited_body, provenance
  copy-through, reject, 409 on re-accept / re-reject, 400 on unknown
  category, prefs round-trip with merge semantics.

Frontend:
- src/components/pilot/script/TemplatizePrompt.tsx — modal showing the
  drafted script with proposed parameters in the Phase 5
  ParameterizationPreview, editable name/category/description, an
  individual-parameter remove button, and the "don't ask again" opt-out.
  Accept posts to /draft-templates/{id}/accept + optionally PATCHes
  preferences. Skip posts /reject.
- src/api/draftTemplates.ts — typed client plus accountPreferencesApi.
- AssistantChatPage: after a successful Resolve (external OR local),
  fetches preferences + pending drafts for the session and queues the
  modal one draft at a time. Escalate does not trigger this flow.
- Sidebar: Scripts nav shows the pending-draft count as a badge. Fetched
  independently of the main sidebar stats so endpoint flakes don't
  break the rest of the sidebar.

Verified live 2026-04-22: seed two drafts → GET sees both pending →
accept draft A (template created, provenance CW #99123 populated) →
reject draft B → pending count drops → PATCH opt-out → GET confirms
persistence.

+**Verified on 2026-04-22:**
+- `GET /draft-templates?pending_only=true` returns pending rows; filter
+  flips the set to include accepted/rejected for audit views.
+- `POST /{id}/accept` → creates `script_templates` row; `source_session_id`,
+  `source_user_id`, `source_ticket_ref` (e.g. "CW #99123") copied from
+  the source session so the Script Library provenance chip has its data.
+  Draft flips to `status='accepted'`, `promoted_template_id` populated,
+  `resolved_at` set. 409 on a re-accept.
+- `POST /{id}/reject` → flips to `status='rejected'`, `resolved_at` set.
