fix(data): Recover 4338 objects from model-archive-disabled-20260305-1136

Root cause: WBS data (3,212 objects) never committed to git.
When Cosmos DB lost data (March 2 key rotation), only git-tracked
files (13 WBS objects) were restored, resulting in 75% data loss.

Recovered from: model-archive-disabled-20260305-1136 (Feb 28 archive)
Source date: February 28, 2026
Objects recovered: 3254 (total now 4338, was 1,084)

Key layers restored:
- WBS: 3,212 objects (was 13)
- Literals: 458 objects (was 375)
- Infrastructure: 46 objects (was 23)
- Screens: 50 objects (was 46)
