feat(panel): surface dev-build version in UI, bot, and CLI

A dev build now shows its `dev+<commit>` identity instead of a misleading stable-looking version in the sidebar badge, dashboard card, update modal, Telegram status report, startup log, and `x-ui -v`. Adds a shared formatPanelVersion helper (single v prefix; dev labels shown verbatim) and fixes the mobile-tag double-v.

Renames the version getters for clarity: config.GetVersion to GetBaseVersion (raw embedded version), config.GetReportedVersion to GetPanelVersion (advertised/displayed), and the xray process GetVersion to GetXrayVersion.
