test(mutual): 钉死 fixture 时间基准，消除时段性 flaky

fixture 用 2024-03-09 固定 ISS TLE + System.currentTimeMillis() 起点；SGP4 带阻力衰减 942 天后高度仅 ≈262km，12h 窗口内可能无广州过境 → 3 条依赖过境窗的用例时段性失败（Gradle 缓存 FROM-CACHE 会掩盖上一次的真跑）。

- TestOrbits.FIXTURE_BASE（2024-03-10T00:00Z，历元后约 18h）取代默认 System.currentTimeMillis()

- MutualViewModel 墙钟可注入：nowMillis: () -> Long = System::currentTimeMillis（第 4 个默认参数，生产行为逐位不变；工厂具名构造零改动）

- 断言里的 now 改用同一基准；prefill/scroll 测试不碰时间未动

修后：:feature:mutual 28/28，全量 ./gradlew test 451/451。
