fix: remove TODOs and implement production-ready code (#425)

This commit addresses several TODOs in the cortex CLI application:

## cortex-app-server/src/share.rs
- Implemented user_id extraction from auth context in create_share()
- Implemented ownership verification in revoke_share() with proper
  authorization checks:
  - Owner can revoke their own shares
  - Non-owners get 403 Forbidden
  - Anonymous shares can be revoked by anyone

## cortex-app-server/src/api.rs
- Replaced AI inline and predict endpoints with proper NotImplemented errors
- Added documentation explaining these features require LLM provider integration
- Updated function signatures to use underscore-prefixed params (no unused warnings)

## cortex-engine/src/agent/orchestrator.rs
- Implemented ApproveModified handling with proper serde_json::Value checking
- Implemented sandbox_used tracking based on policy and risk level
- Sandbox usage now properly reflects Full/Prompt policies combined with
  High/Medium risk levels
