1.5.3

Dynamic Subscription Info: Added Subscription-Userinfo headers and anti-cache controls (no-store) so client apps like v2rayNG always reflect fresh data & quota upon refresh. Separated dummy node endpoints to prevent ID collisions.

Fixed Dashboard Traffic Charts: 24-hour continuous timeline rendering with smooth lines, dynamic Y-axis byte scaling, and responsive hover tooltips (even with zero initial traffic).

Reliable OTA Updates: Added proper User-Agent headers for GitHub Releases API to ensure new versions are accurately detected and applied.

Hardcoded Official Repo: Fixed the OTA repo target permanently to youdidking/stanngv2 and removed user-facing repo input from Settings for stability.
