Remove Cascade double-VPN (v2.3.0).

Drop cascade manager, API, server UI, and i18n keys after unstable egress/routing behavior.

     *   **Reboot** the server directly from the UI.
     *   Strictly concurrent protocol status polling — all supported protocols/services checked in parallel for immediate feedback.
     *   **Asynchronous Processing**: Resilient, non-blocking background architecture prevents the UI panel from freezing, even if remote endpoints hang.
-*   **🔁 Cascade (double VPN)**:
-    *   Route clients through an **entry** AmneziaWG/WireGuard server to an **exit** server (country-block bypass).
-    *   Approach inspired by [ryderams/amneziawg-cascade](https://github.com/ryderams/amneziawg-cascade) (AWG2 entry→exit); applied via panel SSH — **no remote curl|bash** script download.
-    *   Handshake wait + optional egress verify (curl --interface → ifconfig.me); exit return route persisted like ryderams vps2.
-    *   Users keep using the **ENTRY** client config only — do not share the exit cascade peer.
 *   **🧩 Marketplace & Templates**:
     *   Market templates provide quick presets for installing and configuring supported protocols and services (including **Hysteria 2**).
     *   Multi-protocol management lets you run and control multiple protocol instances on the same server.

 ## 📋 Fix / changelog (this fork)
 
+### v2.3.0
+*   **Cascade removed** — double-VPN feature dropped from the panel (manager, API, UI, i18n).
+
 ### v2.2.1
 *   **Cascade egress verify fix**: bind curl to ENTRY `awg0`/`wg0` IP (client-subnet policy route), not cascade peer Address.
 *   Soft-warn (no rollback) when policy route via `cascade` is OK but public-IP echo services fail.
 
 ### v2.2.0
-*   **Cascade (double VPN) restored** — stable entry→exit tunnel for AmneziaWG / WireGuard.
+*   **Cascade (double VPN) restored** — later removed in **v2.3.0**.
-*   Inspired by [ryderams/amneziawg-cascade](https://github.com/ryderams/amneziawg-cascade); logic runs over panel SSH (**no remote curl|bash**).

-*   UI on the server page with per-step settings (pin exit route, MSS clamp, verify egress, …). Defaults prefer **awg2**.

-"""Cascade (double-VPN) between two panel-managed WireGuard/AWG servers.
-
-Traffic path:
-  Clients → Entry server (accessible) → Exit server (blocked / target) → Internet
-
-Implemented inside the entry Docker container as a second AWG/WG interface
-(`cascade.conf`) with source-based routing for the VPN client subnet.
-
-Inspired by ryderams/amneziawg-cascade (AWG2 entry→exit), but executed via the
-panel SSH session — no remote curl|bash script download.
