Fix list#Tools service - remove hard-coded PopCommerce filter and add recursive screen discovery

- Remove hard-coded PopCommerce filter from list#Tools service
- Add proper recursive screen discovery using processScreenWithSubscreens function
- Update MCP routing to use list#Tools instead of mcp#ToolsList for tools/list endpoint
- Now discovers ALL screens from AuthzCheckView instead of just PopCommerce
- Implements proper hierarchical tool naming with dot notation for first-level subscreens
- Supports cross-component screen discovery (PopCommerce → SimpleScreens, etc.)
- MCPJam inspector can now connect and discover 100+ screen tools

This resolves the issue where tools/list returned 0 tools instead of discovering
all accessible screens recursively across all components.
