"""ORCH-067 — Group C: clickable issue number in the live card (AC-10/AC-11/AC-14).

The issue number in the card header is now a Plane hyperlink
(``<a href=".../issues/<id>/">ORCH-NNN</a>``) when a usable browser URL can be
built, and degrades fail-safe to the html-escaped raw number when any piece is
missing (web base / non-loopback / workspace / project_id / plane_issue_id). The
card must NEVER break under parse_mode=HTML: a title with '<'/'&'/'>' stays
escaped while the <a> markup stays valid. Network is isolated (no HTTP from the
render path here); the DB is a temp SQLite.

Test ids TC-10, TC-11, TC-16 from 04-test-plan.yaml.
