Move to nuxt3

[karpikpl]

Updated code to use Nuxt3.
Resolved all old dependencies.

I tried to keep as much backward compatibility as possible:

• kept old port
• kept environment variable names

Warning

One breaking change is required to have NUXT_SESSION_PASSWORD (at least 32 characters long) which is used to encrypt session cookies.

This pull request includes several changes to improve the deployment process, update environment variables, and streamline the Docker configuration. The most important changes include modifications to .env variables, Dockerfile updates, and workflow adjustments.

Environment Variables Update:

• Updated environment variables in .env to use NUXT_PUBLIC prefix instead of VUE_APP, and added new variables for GitHub OAuth and session password.

Docker Configuration:

• Updated Dockerfile to support different build modes (prod and playwright) and re-mapped environment variables for backwards compatibility.

Workflow Adjustments:

• Simplified GitHub workflows by removing redundant steps and adding new steps for building and testing the application. Changes include removing push_proxy_to_ghcr job and updating metadata-action configurations. [1] [2] [3] [4] [5] [6] [7]
• Updated Playwright workflow to include a build step and consolidated Docker-based Playwright tests. [1] [2]

Documentation:

• Updated DEPLOYMENT.md to reflect changes in environment variables and deployment options, and removed references to the legacy -with-proxy image. [1] [2] [3] [4]

Miscellaneous:

• Added .vscode/launch.json for debugging configurations in Visual Studio Code.
