## Summary
Update the `/delete` endpoint reference to match the current web server
handler.
## Details
The endpoint docs still described a `type` form field and the old
`Deleted successfully` response. The handler now accepts either `path`
for a single item or `paths` as a JSON array for multi-delete, infers
file versus folder from the SD card entry, and returns `All items
deleted successfully` when all deletes complete.
This updates the curl examples, parameter table, success response, and
error response list to match the implemented behavior.
## Validation
- Compared the documented parameters and response strings with
`CrossPointWebServer::handleDelete()`
- `git diff --check`
