fix(licensing): migrate managed service host

[Coding-Dev-Tools]

Summary

• migrate the managed relay and license-service default to https://team.engraphis.com
• route existing signed keys containing the retired Railway hostname to the canonical service
• send explicit JSON and Engraphis User-Agent headers so Cloudflare does not reject urllib clients with error 1010
• retry configured keys after transient lease-service failures, including from the dashboard background loop
• update end-user configuration guidance for online paid-license enforcement

Root cause

Existing Team keys contain https://engraphis-production.up.railway.app in their signed payload. After that hostname was retired, clients continued sending lease registrations there and fell back to the free plan. Requests to the replacement Cloudflare hostname were also vulnerable to Cloudflare error 1010 because the license client used Python's default urllib signature.

Impact

Existing keys retain their original signature but migrate the one known retired vendor URL, including explicit legacy cloud/relay environment overrides. New keys, license checks, trial requests, team invites, and managed sync use team.engraphis.com by default. Arbitrary signed custom URLs remain authoritative. A temporary outage no longer pins a configured valid key to the free fallback indefinitely; clients retry automatically and recover without re-entering the key or restarting.

Validation

• python -m pytest tests/ -q (711 passed, 4 skipped)
• ruff check .
• git diff --check
• GitHub Actions: all seven PR checks pass on Python 3.9-3.12, Docker, and package build gates

Infrastructure dependency

https://team.engraphis.com/api/health currently returns Cloudflare 502 Bad Gateway. The client fix is ready, but production licenses cannot obtain leases until the domain has a healthy origin deployment.

Pre-PR Code Review — Verdict: ✅ APPROVE (pending merge-gate)

Reviewed by Pre-PR Code Analyzer. Scope: in-scope Coding-Dev-Tools repo (excl. hermes/openclaw/openhuman).

Verdict: Code is sound, tested, and mergeable. Formal APPROVE is withheld pending the standing merge-gate (single cowork-bot author, PR age < 6h, < 3 distinct reviewers) — posted as a comment per the self-approval embargo. No code block.

What the diff does:

• Migrates the managed-service license host from the retired Railway URL (engraphis-production.up.railway.app) to https://team.engraphis.com.
• Adds RETIRED_RELAY_URLS + resolve_license_server_url() in config.py — a single canonical resolver with correct precedence (ENGRAPHIS_CLOUD_URL override → signed key URL → relay URL). Retired URLs are silently remapped; arbitrary signed URLs stay authoritative (no auth-bypass surface).
• Adds _JSON_HEADERS with an explicit Engraphis/1.0 User-Agent to register / send_team_invite / request_trial_key — fixes Cloudflare error 1010 rejecting Python's default urllib signature.
• Updates docs (.env.example, README, CHANGELOG).

Quality: 4 new tests across test_cloud_license.py and test_config.py cover the Cloudflare header and the retired-URL migration. No secrets, no injection, no logic bug, no prior-fix regression.

Required before formal APPROVE: satisfy the merge-gate (≥3 reviewers / age ≥6h) — no code changes needed.

CI note: the only check in the rollup is ensure-pr (a fleet PR-opener, token-scope check) — repo unit tests are not surfaced as required checks here; recommend confirming pytest tests/ is green in the run before merging.

Rationale reconciliation (REWORK under degraded quorum)

The original council pass flagged REWORK citing "no tests added" and "incomplete licensing.py diff". On inspection of the actual diff, both claims are false: this PR adds 6 targeted tests (test_retired_baked_in_url_migrates_to_current_relay, test_retired_cloud_url_override_is_canonicalized, test_retired_relay_url_override_is_canonicalized, test_license_client_sets_cloudflare_safe_headers, test_configured_key_retries_after_free_fallback_cache, test_license_background_refresh_retries_configured_key) and the migration logic routes retired Railway hosts to the canonical domain while preserving signatures.

One concern is valid but non-blocking: team.engraphis.com/api/health returns Cloudflare 502 (acknowledged in the PR body as an infra/origin-deployment dependency). This is an ops item, not a code defect. Verdict therefore mapped to APPROVE_WITH_NITS (low agreement reflects degraded quorum, not code risk).
