test(palier-2): 13 tests — webhooks, SSE, étiquettes, milestones (65 verts)

FakeGitea: labels (repo_labels/label_ops), milestones (Sprint 1 sur
issues 1 et 3), invalidate_cache compteur. Le flux SSE est testé au
niveau du générateur: les clients de test HTTP ne ferment pas
proprement un flux infini (vérifié empiriquement); le bout-en-bout
HTTP a été validé en smoke test réel (curl + webhook).
