Summary

• Register the existing RIP-302 Agent Economy routes from the integrated node app so /agent/stats and /agent/jobs no longer 404 for the explorer dashboard.
• Register/read through Ergo anchor routes when available, and provide a read-only /anchor/list fallback plus /anchors redirect so navigation does not land on 404.
• Ensure anchor listing creates the ergo_anchors table on empty DBs and returns an empty list instead of failing.

Fixes the application-route 404s reported in #6693. The raw-IP certificate mismatch is deployment/certificate configuration, not something this repo patch can correct by itself.

CI note: the broad test workflow is failing on pre-existing/broader baseline tests outside this PR scope (bridge/governance/beacon/monitor/docs/etc.). The focused route coverage for this PR passed locally:

Reviewed the route-registration fix for #6693. The main happy path looks reasonable: the Agent Economy routes are registered on the integrated app, /anchors gives the explorer a stable navigation target, and /anchor/list now handles an empty anchor DB instead of 404/failing.

One non-blocking test gap below: the fallback branch is part of the behavior this PR is relying on for deployments where the optional anchor module cannot import, but the current integrated-app test does not force that branch. Adding a small import-failure/monkeypatch test would make this safer to merge.

Routing this as a substantive line-level review for rustchain-bounties #73; no RTC has been received for this review yet.

[Asti1982]

This fallback branch is now part of the explorer's availability guarantee, but the added integrated-app test only exercises it if rustchain_ergo_anchor happens not to import in the test environment. Since the module normally imports, the fallback query parsing/table-creation path can regress without failing CI. Consider adding a focused test that forces the optional anchor import/registration to fail and then asserts /anchor/list still returns 200 with the empty payload plus the expected 400 responses for invalid limit/offset.

[Asti1982]

Good extraction here: using _ensure_anchor_table(cursor) before the list query keeps /anchor/list aligned with get_last_anchor() on empty deployments. That matters for the explorer fix because a fresh DB should render an empty anchor list instead of surfacing a route-level error to first-time users.
