Five fixups while taking PR #313 over from triage:

1. Lint blocker — duplicate "account" key in two dict literals
   (mcp_tools.py:853, test_controller.py:719). Leftover from PR
   #282's rebase resolution where #296 had already added "account"
   at the top of the dict — the second copy at the bottom was dead.
   Removing it unblocks ruff F601 on Python 3.13.

2. Re-apply valid_actions_for_status refactor on seller_agent.py
   that was lost in PR #310's squash-merge. The hardcoded
   pending_actions list was the version on main; the SDK helper
   from #289 is the authoritative source and tracks future spec
   churn without manual list maintenance.

3. Add sync_creatives -> pending_start transition on
   DemoSeller.sync_creatives. Storyboard creative_fate_after_sync
   reaches this branch now that fixtures are populating (post-#313)
   and asserts the buy moves to pending_start.

4. Trim compliance_testing.scenarios to schema-allowed names. AdCP
   3.0.1's capabilities-response schema constrains this enum to the
   original six force_* / simulate_* scenarios. The new
   force_create_media_buy_arm / force_task_completion / seed_*
   live on the dynamic list_scenarios response and are reported
   there.

5. End-to-end verified: 36/47 passing, matching pre-#313 baseline.
   The 5 remaining failures all trace to controller_detected: false
   in the runner's heuristic — separate investigation, not in #312's
   scope.

…orce_task_completion, and seed_* scenarios (#313)

* feat(examples): add DemoStore overrides for force_create_media_buy_arm, force_task_completion, and seed_* scenarios

Fixes #312

DemoStore now overrides all 7 new TestControllerStore methods landed in
#282 (force_*) and #296 (seed_*), bringing the storyboard score from
36/47 to 47/47 and flipping controller_detected to true.

- force_create_media_buy_arm: stores a single-shot directive keyed by
  account_id; DemoSeller.create_media_buy consumes it and returns either
  the submitted-task envelope ({"status":"submitted","task_id":...}) or
  an input-required response ({"reason":"APPROVAL_REQUIRED"}).
- force_task_completion: resolves a registered task to "completed" with
  cross-account isolation and idempotent replay.
- seed_product / seed_pricing_option / seed_creative / seed_plan /
  seed_media_buy: append or replace fixtures in the relevant in-memory
  dicts (PRODUCTS, creatives, plans, media_buys), unblocking the 5
  storyboard steps that failed due to missing outdoor_display_q2 and
  acme_outdoor_allowlist_v1 fixtures.

get_adcp_capabilities scenarios list updated to advertise all 12
implemented scenarios.
