feat: Implement database backup (import/export) and refactor module structure

This commit introduces a new backup feature for database import and export across all supported platforms, reorganizes core modules into feature-based structures, and updates dependencies to use official KMP artifacts.

- **New Feature: Database Backup**:
    - Created `feature:backup:domain` and `feature:backup:ui` modules to handle database import/export logic and UI.
    - Implemented platform-specific `DatabaseFilePicker` and `DatabaseFileTransfer` using Okio for file operations (WASM excluded).
    - Added `ExportDatabaseUseCase` and `ImportDatabaseUseCase` to manage database states and file copying.
    - Added new settings category for "Backup" with export/import actions in `SettingsDetailScreen`.
    - Integrated backup functionality into `SettingsViewModel` and added relevant localized strings.

- **Refactor & Module Reorganization**:
    - Renamed and moved `core:data:file-explorer` to `feature:file-explorer:data`.
    - Removed vendored `thirdparty:androidx:paging:compose` in favor of the official `androidx.paging:paging-compose` (version 3.4.0) now supporting KMP.
    - Reorganized `sharedModules.kt` and `uiTestModules.kt` to include new backup use cases and test mocks.

- **Test Infrastructure**:
    - Added `BackupFeatureTestCase` for integration testing of the import/export flow.
    - Implemented `createTempBackupPath` expect/actual utility for cross-platform test file management.
    - Updated `AndroidUiTests` and `DesktopUiTests` to include the new backup feature test.
    - Added `TestDatabaseFilePicker` for headless UI testing of file selection.

- **Build & Dependency Updates**:
    - Updated various dependencies: `androidSqlCipher` (4.13.0), `kotlinx-serialization` (1.10.0), and `androidx-paging` (3.4.0).
    - Switched internal library references from direct `compose` properties to `libs.compose` version catalog entries for better consistency.
    - Added `disableIosReleaseTasks` utility to convention plugins to optimize CI test builds.

- **Bug Fixes**:
    - Updated `OffsetQueryPagingSource` in SQLDelight paging implementation to fix `getRefreshKey` calculation.
    - Fixed `ChangePasswordUseCase` logic to handle null/empty password scenarios correctly.
