feat(drawer): change drawer layout to dropdown ui

Resolves #9189

Depends on #9358

This changes the drawer ui to a true dropdown ui solution, hidden behind a feature flag.

## Main Features

1. **Unified Folder Support**:
   - Added a unified account view that aggregates content from multiple accounts
   - Implemented a unified inbox that shows messages from all accounts in one place

2. **Drawer Layout Improvements**:
   - Added support for two drawer UI modes: dropdown drawer and side rail drawer to keep changes minimal when the feature flag is not enabled
   - Improved folder selection and navigation between accounts
   - Enhanced the account list view with better selection states

3. **UI/UX Enhancements**:
   - Fixed selection state for nested folders
   - Improved avatar color selection for dark mode

## Technical Changes

1. **Architecture**:
   - Created a dedicated repository for unified folders (`UnifiedFolderRepository`)
   - Implemented search functionality to support unified inbox views
   - Added proper message counting for unified folders
   - Created new domain entities: `UnifiedDisplayAccount`, `UnifiedDisplayFolder`, and `UnifiedDisplayFolderType`

2. **Bug Fixes**:
   - Fixed issues with folder selection in nested folders
   - Fixed account selection to only trigger when the account is different
   - Removed deselect functionality that was preventing folders from being selected
   - Fixed management of folders when unified account is shown

3. **Feature Flags**:
   - Added feature flags to control the drawer functionality:
     - `enable_dropdown_drawer`: Controls the overall drawer feature (dropdown vs. side rail)
     - `enable_dropdown_drawer_ui`: Controls the UI mode (dropdown with expandable folders vs. side rail with expandable folders)

| Name       | Screenshot                                  |
|-----------------------|----------------------------------------------------|
| Unified Account          |  |
| Account List          |  |
| Account View         |  |
| Account View with nested selection         |  |

Dropdown Drawer - change the account selection UI to dropdown list
The account selection should open a dropdown list of accounts instead of the siderail.
