notify_approve_requested now embeds two HTML <a> links into the single
notifying approve-gate message: a Gitea branch-view link to 01-brd.md and a
Plane issue browser link. Adds ORCH_PLANE_WEB_URL (external Plane web URL,
fallback to plane_api_url) with a loopback-guard that omits the Plane link
when the resolved base is localhost/empty (no broken localhost URLs in prod).
Each link is built independently and omitted on missing data; the message and
the "flip to Approved" call to action are always sent as exactly one ping. The
shared send_telegram helper is left untouched (min blast radius for the
self-hosting prod container). Dynamic labels are html.escaped; parse_mode=HTML
preserved. QG registry / stages / approve handler unchanged.
Docs updated in-PR: CHANGELOG, .env.example, INFRA env map.
Tests: test_notify_approve_links.py, test_analysis_approve_flow_links.py.
