### Describe the Bug

`wrangler ai finetune` has no single read or delete command/endpoint for LoRA adapters.

```
Interact with finetune files

COMMANDS
wrangler ai finetune list List your finetune files
wrangler ai finetune create Create finetune and upload assets

GLOBAL FLAGS
-c, --config Path to Wrangler configuration file [string]
--cwd Run as if Wrangler was started in the specified directory instead of the current working directory [string]
-e, --env Environment to use for operations, and for selecting .env and .dev.vars files [string]
--env-file Path to an .env file to load - can be specified multiple times - values from earlier files are overridden by values in later files [array]
-h, --help Show help [boolean]
--install-skills Install Cloudflare skills for detected AI coding agents before running the command [boolean] [default: false]
-v, --version Show version number [boolean
```

I cannot delete any singular LoRA adapter if I choose to not use it, or I cannot retrieve any singular LoRA adapter I have already uploaded. The lack of REST endpoints / wrangler commands available makes development extremely difficult when trying to test out different LoRA adapters. Curious if either is planned.

### Please provide any relevant error logs

Commencez par localiser les points d’entrée existants des commandes `wrangler ai finetune list` et `create`, ainsi que les opérations REST qu’elles utilisent. Confirmez la forme de l’API pour la lecture et la suppression d’un seul adaptateur, puis définissez l’achèvement comme des commandes de lecture et de suppression fonctionnelles, avec une couverture des cas de réussite et d’échec pertinents.
