v2.1.0-beta.6

Live stats charts got their time axis wrong in three different ways.

Fixes

• The CPU, RAM and bandwidth charts kept a fixed number of points and called it two minutes. Plex samples every 5 seconds rather than the 6 the code assumed, and bandwidth rows only exist for seconds that moved bytes, so one chart came up short and the other ran long. They window by time now.
• Timestamps came straight from the media server. A Plex box or an SSE plugin host with a drifting clock would put points in the future or pile them against one edge. Tracearr re-stamps them on arrival, and leaves a server's own timestamps alone when its clock already agrees.
• A break in reporting was drawn as a straight line between the points either side, so a server that went quiet looked like it was holding steady. Gaps longer than 15 seconds now break the line instead.

Security

• Four dependency advisories fixed. Two others sit in build tooling that never ships with Tracearr and have no upstream fix yet.
