fix: Restore validate_v16.py doc paths after CURRENT/CATALOGS reorg (AGENTS.md §3)

Changes:
- Update CSV references from docs/v16_0/ to docs/CURRENT/CATALOGS/
- Rename 08_DETAILED_WBS_MASTER.csv → WBS_MASTER.csv
- Rename FE_COMPONENT_CATALOGUE.csv → FE_COMPONENT.csv
- Add explicit UTF-8 encoding to JSON read (fixes cp949 decode error on Windows)

CI was failing at static/validate_v16.py step due to docs reorganization not reflected in validator.
Local test (python tools/validate_v16.py):
- Before: FAIL=18 (missing CSV paths)
- After: FAIL=2 (unrelated source archive issues, pre-existing)

Fixes AGENTS.md rule 20 'Never claim build/test passed without evidence'.
