Reporting: there's no complete list of possible report types (or named reporting endpoints)

### MDN URL

https://developer.mozilla.org/en-US/docs/Web/API/Reporting_API

### What specific section or headline is this issue about?

Report types [but also others]

### What information was incorrect, unhelpful, or incomplete?

I could not find a complete list report types (or at least the current text doesn't tell me if the listed report types are exhaustive).

### What did you expect to see?

On this page, I expected to find a complete list of all the possible values for a report body's `type` property. Short of that, I expected to be able to piece together the list from the [ReportingObserver: observe() method](https://developer.mozilla.org/en-US/docs/Web/API/ReportingObserver/observe) page and the [Reporting-Endpoints header](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Reporting-Endpoints) page.

Likewise, I expected to find a complete list of named reporting endpoints (e.g., `Reporting-Endpoints: crash-reporting="…"`), plus the `default` endpoint.

Without this information, it's very difficult to know what reports one might expect to receive via the `ReportingObserver` API or via `POST` to a `Reporting-Endpoints: default="…"` header URL.

Finally, I would also expect to see an explicit enumeration of which reports types go to reporting endpoints, the `ReportingObserver` API, or both.

### Do you have any supporting links, references, or citations?

The [Report types section](https://developer.mozilla.org/en-US/docs/Web/API/Reporting_API#report_types) says:

> The type of report can be determined from its `type` property, which for the reports above would be `coep`, `deprecation`, `integrity-violation`, `intervention` and `csp-violation`.

It does not say whether "the reports above" is an exhaustive list of report types.

The relevant specs are in a deeply confused state, so it's not easy to determine this from the specifications (see https://github.com/w3c/reporting/issues/216#issuecomment-2967834156 and that issue in general for more information).

### Do you have anything more you want to share?

_No response_
