Bug report

### Description

# Context
When deploying an app (using KV and working ok in dev env with local KV) to deno deploy EA(free tier) via the github repository, **but without provisioning a kv db**.

# problem
- no error on logs on builds processes
- the apps runs
- but data are stored somewhere for the scope of this session, but starts again with an empty data on other requests (e.g. forced refresh, new browser connections,...)

### Steps to reproduce (if applicable)

1. Use the astro[demo astro kv template ](https://github.com/denoland/deno-astro-template)
2. Change the data to be using KV in the code, as explained in the github repo of the template
3. Deploy with github action on denoDeployEA ( **without provisioning a kv db for the app)
4. Connect to the app and test

### Expected behavior (if applicable)

Well I'd expected on error or alert msg of the type " no KV DB provisioned, please follow the following steps to sort it out..."

### Possible solution (if applicable)

_No response_

### Additional context

_No response_

Start with the deno-astro-template reproduction and its GitHub deployment path, then deploy the KV-using app without provisioning a KV database. Compare the build and runtime behavior with the expected missing-database condition. Done means the deployment or app clearly reports that no KV database is provisioned and explains the next steps.
