feat(icons): import 7Soul1 status icon library

[zoeyrose]

Closes #229

Summary

• import the complete 7Soul1 496-icon CC0 library under a stable icon_7soul1_* namespace with per-file provenance;
• replace every fixed player-status face with the issue's mapped source and coherent 32x32 treatment; and
• preserve source-derived consumable faces and generic/internal fallback faces.

Coordination

The matching Classic consumer change is delivered in a separate pull request against atrinik/classic@main and is linked to this issue without adding another closing path. The content pull request owns the authored assets, archetypes, maps, provenance, and runtime collection inputs.

Validation

• python3 tools/validate.py
• git diff --check
• target-specific runtime collection and the coordinated Classic build/test recipe described in the final delivery handoff.
