Chore: monorepo setup

[compojoom]

What it solves

This PR restructures the repository into a monorepo format to facilitate code sharing between the mobile app and web app. The mobile app code will be added in a subsequent update.

While this PR touches many files, the changes are straightforward and easy to review commit by commit:

• First Commit: Moves existing files into the monorepo structure (apps/web).
• Second Commit: Sets up the monorepo configuration.
• Third Commit: Updates and fixes GitHub Actions to align with the new structure.

How to test it

1. Clone the repository.
2. Run yarn from the root directory to install dependencies and set up the monorepo.
3. Start the web app using one of the following options

• From the root directory:
  yarn workspace @safe-global/web start

• From the apps/web directory:
  yarn start

Checklist

• I've tested the branch on mobile 📱
• I've documented how it affects the analytics (if at all) 📊
• I've written a unit/e2e test for it (if applicable) 🧑‍💻

📦 Next.js Bundle Analysis for @safe-global/web

This analysis was generated by the Next.js Bundle Analysis action. 🤖

⚠️ Global Bundle Size Increased

Page	Size (compressed)
global	1 MB (🟡 +12.25 KB)

Details

The global bundle is the javascript bundle that loads alongside every page. It is in its own category because its impact is much higher - an increase to its size means that every page on your website loads slower, and a decrease means every page loads faster.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

Details

Only the gzipped size is provided here based on an expert tip.

First Load is the size of the global bundle plus the bundle for the individual page. If a user were to show up to your website and land on a given page, the first load size represents the amount of javascript that user would need to download. If next/link is used, subsequent page loads would only need to download that page's bundle (the number in the "Size" column), since the global bundle has already been downloaded.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

Next to the size is how much the size has increased or decreased compared with the base branch of this PR. If this percentage has increased by 20% or more, there will be a red status indicator applied, indicating that special attention should be given to this.

Is there a difference to navigating into an app and running yarn add <package-name> there directly?

[compojoom]

No. When you execute the command it would run in the package directory context (meaning root will be the directory). Sometimes the output coloring is a bit off and yarn is adding some prefixes to every line (but I can't tell you when this exactly occurs)
