新增网络测试功能，预留付费用户线路自定义与线路自选入口 #8

This PR adds a Network Test page, introduces a “skip update prompt for 5 days” flow, and surfaces update availability in Settings with a blinking dot.

Main actionable issue: UpdateService.checkForUpdate() can leave _checking stuck true on early returns, effectively disabling future checks. Additional recommendations relate to probe implementation (use HEAD/lightweight endpoints), clearer privacy disclosure for third-party IP lookups, minor UI clarity, and launchUrl failure handling.
