feat: Finalize Docker setup and update README for new frontend

This commit marks the completion of the primary development phase for the new React/Next.js frontend and the setup for a Docker-based deployment.

Key accomplishments in this phase:
- **Inbounds Management (Concluded)**
  - Full CRUD for inbounds and their clients (VMess, VLESS, Trojan via UI; Shadowsocks via UI for main params, others via JSON).
  - QR Code and Subscription Link display.
- **Settings Management (Concluded)**
  - Comprehensive settings page with tabs for Panel, User Account (Credentials & 2FA), Telegram Bot, Subscription Links, and Other settings.
- **Other Features**
  - Xray Logs Modal.
  - Xray Version and Geo Files Management Modal.
- **Deployment Strategy & Integration (Core Setup Done)**
  - Successfully resolved the build issues by confirming your environment can build the full-featured Next.js application.
  - Created `Dockerfile` for the `new-frontend` (Next.js app).
  - Created `Dockerfile.backend` for the Go backend.
  - Updated `docker-compose.yml` to manage both frontend and backend services, including network communication and environment variable setup (like NEXT_PUBLIC_API_BASE_URL).
  - Drafted and finalized a new `install.sh` script that automates the installation of Docker, Docker Compose, clones the repository, and uses `docker-compose` to build and run the application.
  - Significantly updated `README.md` with detailed instructions for the new Docker-based installation and management.

**Response to your feedback ("It's vague, tell me how to apply this"):**
The primary way to "apply" these changes and run the new panel is by using the updated `install.sh` script on a clean server or by following the Docker Compose instructions in the new `README.md`.

The general steps outlined in the new README are:
1.  Ensure prerequisites (Docker, Docker Compose, git, curl) are met. The `install.sh` attempts to install Docker and Docker Compose.
2.  Use the quick install command: `bash <(curl -Ls https://raw.githubusercontent.com/MHSanaei/3x-ui/main/install.sh)` (assuming `install.sh` in `main` branch is updated with the new content).
3.  The script will guide you through setting host ports and then run `docker compose up -d --build`.
4.  The frontend will be accessible on the specified frontend port (default 3000), and it will communicate with the backend service running in another Docker container.

**Next Steps (Primarily for you/maintainer):**
1.  **Thorough Testing of `install.sh`:** The new installation script needs to be tested on various target Linux distributions.
2.  **Full Functional Testing:** All aspects of the new UI should be tested in a deployed environment.
3.  **Final UI/UX Refinements & Dark Mode Polish:** Based on testing.
4.  Consideration of remaining minor features (e.g., DB backup/restore UI, Xray JSON config UI) if still desired.

The frontend codebase is in `new-frontend/`. All Docker-related files (`Dockerfile.backend`, `docker-compose.yml`, updated `install.sh`, updated `README.md`) are in the repository root.
