Subject: [PATCH] feat(03-02): create FieldRenderer and AzureAuthToggle

- FieldRenderer: registry-driven input renderer (text, password, select, hidden provider)
- AzureAuthToggle: segmented SAS/Key toggle, defaults to SAS, both fields always registered via CSS show/hide
- Both fields preserved on toggle (no conditional rendering that would lose react-hook-form state)
