…gement UI

This commit integrates the server control panel into the main settings flow for administrators and enhances the server management screen by categorizing active and saved connections.

### Key Changes:

*   **Settings & Administration**:
    *   **Control Panel Access**: Added a new entry point for administrators in the `SettingsScreen` header, launching the `ControlPanelView` within a dialog.
    *   **ViewModel Integration**: Updated `SettingsViewModel` and its UI state to track `isAdmin` status, the `serverId`, and the currently `activeServer` object.
    *   **Lifecycle Management**: Implemented a `LaunchedEffect` in the settings screen to initialize the `ControlPanelViewModel` whenever the active server ID changes.

*   **Server Management UI (`ServerManagementScreen.kt`)**:
    *   **Sectioned List**: Refactored the server list to visually separate the "Active Server" from "Saved Servers" using new `ServerSectionHeader` components.
    *   **Conditional Access**: Updated the Jellyfin server details tab to disable the Control Panel button for inactive servers, adding a descriptive label and adjusting visual opacity to reflect availability.

*   **Data & Logic Improvements**:
    *   **Service Status Aggregation**: Enhanced `ServerManagementViewModel` to calculate aggregate `ServiceStatus` (TMDB, Jellyseerr, etc.) for servers that are not currently active, providing better visibility of available features across saved connections.
    *   **Address Filtering**: Refined the secondary address list in the server management view to exclude the primary base URL, preventing redundant display.

*   **UI Components**:
    *   Introduced a new `ServerSectionHeader` for better organizational hierarchy in lazy lists.
    *   Integrated the `ic_admin_panel_settings` icon as a primary action for administrative tasks.

This commit upgrades the project's build infrastructure and several key dependencies to their latest versions, including Gradle, the Android Gradle Plugin, and the Media3 library suite.

### Key Changes:

*   **Build System**:
    *   Updated Gradle wrapper from 9.3.1 to 9.4.1.
    *   Updated Android Gradle Plugin (AGP) from 9.1.0 to 9.2.1.

*   **Core Libraries**:
    *   Updated Kotlin from 2.3.20 to 2.3.21.
    *   Updated Compose BOM from 2026.05.00 to 2026.05.01.
    *   Bumped Media3 (ExoPlayer, Session, and Common) from 1.10.0 to 1.10.1.
    *   Updated `aboutlibrariesCore` to 14.2.0.

…calization

This commit moves hardcoded UI strings, content descriptions, and error messages throughout the server management and control panel screens into `strings.xml`. This improves maintainability and prepares the application for localization.

### Key Changes:

*   **Control Panel (`ControlPanelView.kt`)**:
    *   Externalized strings for server power actions, including titles, confirmation messages, and buttons for Restart and Shutdown dialogs.
    *   Updated active session headers, idle status indicators, and task category labels (e.g., "Running", "Other") to use string resources.
    *   Implemented localized placeholders for unknown devices, titles, and users.

*   **Server Management UI**:
    *   **`ServerCard.kt`**: Moved connection type labels ("Local", "Tailscale", "Remote") and menu options into resources.
    *   **`ServerManagementScreen.kt`**: Refactored section headers for "Active" and "Saved" servers.
    *   **`ServerDetailDialog.kt`**: Updated the `DetailTab` enum to use string resource IDs for tab labels (Jellyfin, Seerr, ABS).

*   **Service-Specific Tabs**:
    *   **Jellyfin**: Externalized administration headers, control panel descriptions, and user count pluralization logic.
    *   **Jellyseerr**: Moved role labels, permission names (Request, Auto-Approve, 4K, Manage), and quota duration strings to resources.
    *   **Audiobookshelf**: Refactored content duration formatting and network connection placeholders to use localized strings.

*   **Resources & Infrastructure**:
    *   Added a comprehensive set of new strings to `strings.xml` covering navigation, actions, status messages, and accessibility descriptions.
    *   Updated `ServerManagementViewModel` to retrieve error messages (e.g., "Address already exists") using `context.getString()`.
    *   Enhanced accessibility by replacing hardcoded `contentDescription` strings with resource lookups across all shared server components.
