Uploading files greater then 500MB to storage fails

### 👟 Reproduction steps

1. Create a new bucket in an empty project
2. Select create file
3. Attempt to upload a file that is over 500MB (750MB-1GB seems to trigger consistently, sometimes ~500MB goes through)
- **NOTE:** Sometimes the first upload will go through but further attempts fail, even after restart of the server
- I have also attempted this with local and S3 storage with similar results in both cases
- Attempted to upload files of size 578.9MB and 1.3GB for testing

### 👍 Expected behavior

File uploads successfully

### 👎 Actual Behavior

File uploads fails with the following error in the appwrite pod if using S3 storage method:
```
Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 5242880 bytes) in /usr/src/code/vendor/utopia-php/storage/src/Storage/Device/S3.php on line 228

```

The same error occurs for local storage method but in `/usr/src/code/vendor/utopia-php/storage/src/Storage/Device/Local.php`

### 🎲 Appwrite version

Different version (specify in environment)

### 💻 Operating system

Linux

### 🧱 Your Environment

- Windows Desktop Dev Environment
- Appwrite 1.9.0 running through Docker Desktop using WSL
- 64GB or ram with at least 32GB available during tests
- Attempted with forced allocation of 16GB through deployment section
- Digital Ocean Appwrite Marketplace Server 1
- Appwrite 1.9.0 running through docker
- Basic Shared CPU instance with 2vCPU and 4GB of ram
- Free ram was between 700-450MB during uploads
- Digital Ocean Appwrite Marketplace Server 2
- Appwrite 1.9.0 running through docker
- Basic Shared CPU instance with 8vCPU and 16GB of ram
- Free ram stayed above 12GB during uploads
- All environments used the same .env with only the domain changed
- GCP Storage was used for testing the S3 storage method

### 👀 Have you spent some time to check if this issue has been raised before?

- [x] I checked and didn't find similar issue

### 🏢 Have you read the Code of Conduct?

- [x] I have read the [Code of Conduct](https://github.com/appwrite/.github/blob/main/CODE_OF_CONDUCT.md)

Start by inspecting vendor/utopia-php/storage/src/Storage/Device/S3.php at line 228 and the corresponding upload path in Device/Local.php. Reproduce the failure with the documented 578.9MB or 1.3GB files in the Appwrite 1.9.0 Docker setup, then verify that local and S3 uploads complete without exhausting PHP memory.
