feat: signal which products are quota limited

[pauldambra]

Problem

In #16725 I changed capture so that we could have posthog-js clients not continue sending session recordings when they were quota limited

But, that meant all older clients would retry traffic that they previously wouldn't have done.

We had to revert that, but still need to reduce load from recordings clients

Changes

• Still return a 200 when dropping events due to quota limiting
• If recordings were quota limited then return a list of limited products in that request as part of the payload

So, the possible responses now are

{"status": 1}

and

{"status": 1, "quotaLimited": ["recordings"]}

I considered more structure in the payload

e.g.

{
    "status": 1,
    "quota_limited": {
        "recordings": {
             "retry-after": 60
        }
    }
}

That would mean we have space to amend this in the future, but this is the first change to response shape in 2 or 3 years, so, it's reasonable to assume that it won't change much from here.

How did you test this code?
