Add licence notices for oracle/pretrained/ and correct its descriptions

oracle/pretrained/LICENSES.md copies the task author's licence notices (yizhouz/frontierphysics-oracle-artifacts at db41dc05): the models were made with MIT-licensed code and code under the Inria/MPII GRAPHDECO research-only licence. The archives carry no licence files, so the README no longer says they do. Each package is described as a copy of the same-named file in the author's folder; the card's licence section, manifest description and pinning note are updated.

 A package holds the trained Gaussian appearance, the saved native simulation trajectory, the fitted physical parameters, the configuration and source records, and the reference submission (`paper.pdf`, `solution/` and `results/`, without rendered frames; `results/metrics.json` is a placeholder). The Oracle (`bash /oracle/solve.sh`, `ORACLE_MODE=pretrained`) downloads the package for its assigned scene from a pinned revision of this repository, checks its size and SHA-256, renders the saved trajectory again on the GPU and recomputes the metrics. It does not train or resimulate. The task's `oracle/pretrained_manifest.json` pins the revision, size and SHA-256 of each package.
