Add interactive 3D PCA views to dashboard Park Mind tab

Two spin/zoom Plotly scatter_3d sub-tabs in the PCA tab:
- Rides in PC1xPC2xPC3 (loadings), color by category / GPS
  k-means area / PC1 busyness. Adds GPS k-means areas to
  compute_pca(), auto-labeling the lowest-PC2 cluster Kiddieland.
- Moments in PC1xPC2xPC3 (per-snapshot scores), color by hour /
  day-of-week / weekend / month, sampled to 15k points if larger.

Pin numpy in requirements (now imported directly).
