Stardance Stats dev log #4

History endpoints.

Projects, users, and the whole platform all run through the same thing. Pick your metrics, pick hourly, daily or weekly, get points back.

Points only get written when a number moves, which means quiet stretches look like gaps. There’s a fill option that carries the last value forward so a flat line renders as a flat line. Ask for too wide a range, and it says no instead of trying.

Every response now says when the data was last seen and whether that’s old. Responses also carry an ETag, so asking again for something that hasn’t changed costs nothing.

Also added a platform endpoint for the site-wide totals, and a single devlog one.
