Refactor frontend modularization by migrating multiple features (profile, security, change password, licenses, sync, activity, admin, plugins, shares, shared with me) into their own modules. Update Koin dependency injection to include the new feature modules and remove obsolete components from the composeApp. Adjust Gradle configurations to reflect the new structure, enhancing code clarity and organization. Update documentation to reflect changes in module ownership and implementation status.

 - **:data:storage** – DTOs split to one file per DTO (StorageItemDTO, CreateFolderRequestDTO, etc.); StorageDTOs.kt removed.
 - **:feature:auth** – Done. Full screen in module: `AuthViewModel`, `AuthError`, `AuthSuccessCallback`, `AuthComponent`, `DefaultAuthComponent`, `AuthContent` (one file per class). Depends on `:core:resources`, `:domain:auth`, Koin Compose ViewModel, Material3; composeApp only wires navigation (RootContent uses AuthContent from module).
 - **:feature:settings** – Done. Full screen in module: `SettingsComponent`, `DefaultSettingsComponent`, `SettingsViewModel`, `SettingsContent`, `SettingsScreen`, `SettingsDialogs`, `SettingsComponents` (one file per class/group). Theme/language via component callbacks; `ThemeMode` in `:core:resources`. Depends on `:core:resources`, `:domain:auth`, Koin Compose ViewModel, Material3. `featureSettingsModule` loaded in all entry points.
+- **:feature:profile** – Done. Full screen in module: `ProfileComponent`, `DefaultProfileComponent`, `ProfileViewModel`, `ProfileContent`, `ProfileScreen`, `ProfileComponents`, `ProfileDialogs`; export wiring delegated through component callback so module remains composeApp-independent.
+- **:feature:security** – Done. Full screen in module: `SecurityComponent`, `DefaultSecurityComponent`, `SecurityViewModel`, `SecurityContent`, `SecurityScreen`, `SecurityComponents`, `SecurityDialogs`.
+- **:feature:changepassword** – Done. Full screen in module: `ChangePasswordComponent`, `DefaultChangePasswordComponent`, `ChangePasswordViewModel`, `ChangePasswordContent`, `ChangePasswordScreen`.

+- **:feature:admin** – Done. Full screen in module: `AdminComponent`, `DefaultAdminComponent`, `AdminViewModel`, `AdminContent`, `AdminScreen`, `AdminComponents`, `AdminDialogs`.
+- **:feature:plugins** – Done. Full screen in module: `PluginsComponent`, `DefaultPluginsComponent`, `PluginsViewModel`, `PluginsContent`, `PluginsScreen`.

 Domain and core modules typically do not define Koin modules (they expose interfaces/types; data/feature modules provide implementations and register them).
