It is famously hard to prove a negative, and China is not going to issue an official statement stating that you haven’t been there, so you’ll need to work with what you have.
In general, from what I’ve seen, the vast majority of immigration checks on where you’ve been rely almost entirely on honest self-declaration, backed up with the force of the law if they catch you lying. Given that you have positive evidence of living somewhere else (your UK residency card), plus a lack of UK/Chinese stamps that would contradict your story, I’d say it’s highly likely they’ll allow you to enter.
The one wrinkle in the ointment is that at time of writing, Timatic does not appear to be aware of the China ban for St Lucia. If/when the ban does come through, the airlines will be looking at this to see if you can enter, and depending on the wording they may or may not allow you to board. So keep an eye on this site for early warning.
