Add "Import a file" in Terminal page

It’s really useful to have the terminal integrated directly into Coolify’s dashboard. The only issue is that we can’t import files into it.

For example, I have a MySQL container running and I’d like to import an SQL file to initialize the project. Since I can’t access my local PC, I have to either upload the file to the cloud or go through a complex setup with SSH tunnels just to import a file.

That’s just one example with a database import, but the same idea could apply to other needs, like importing a zip, gzip, etc.

If this feature ever gets added, here’s how I imagine it could work:

• Add an “Import file” button (maybe with options in the modal, like setting an expiration time for the file, useful if it’s large and will take longer to process).
• Once the file is uploaded, it’s stored in a temporary location.
• A variable, symlink, or similar reference is created to provide the direct path to the uploaded file.
• After that, we can use the file as needed, and it automatically expires after the chosen time.
