Add production deployment, photorealistic movement walls, and fix duplicate influence links.

Configure hosting for gallery.mysuperlab.netcraze.pro and LAN access, enhance movement gallery textures with period-appropriate painted materials, dedupe influenced-by API responses via painting_influence_sources, and refresh several painting image files.

+Both **`influencedBy`** and **`influenced`** are read from **`painting_influence_sources`** only (one row per edge). Painting-type sources appear in *Influenced By* when they are predecessors; in *Influenced* when this painting is the source of a later work. Artist and movement sources appear only in *Influenced By*. The legacy `painting_influences` table is not merged into these responses — it mirrors painting edges for scripts only.
