[IMMUTABLE-UPDATE] Fix: Replace 'organism' with 'composite' in components schema

Updated atomic design terminology in components.schema.json:
- organism → composite

Aligns with corporate terminology requirements while maintaining
the atomic design pattern hierarchy:
atom → molecule → composite → template → page

Justification: Correcting terminology oversight in newly created schema
to match Phase 3 corporate language requirements.
