I know

2 chest X-rays and wasn’t picked up. 2 weeks later a quality assurance type guy picked it up! Plus I had to lie on my front arms up on the CT scan, reckon I took a step back in the healing process
Sorry to hear of your troubles.
There’s an expression in medicine that in the Emergency Department, the sickest are seen by the thickest! Usually, they are staffed by junior doctors fresh out of internship who are “supervised” by registrars and distantly by consultants. If you were walking wounded and treated in minors, you might not have seen a doctor at all.
Sternal fractures aren’t easy to spot on plain xray, but they are common so should be actively sought both clinically and on trauma films. If in doubt, a low-dose CT is a cheap and quick means of establishing the answer and to exclude underlying lung or mediastinal injury. It should be readily available from ED.
Eventually, all ED xrays are reported by a radiologist and then calls are made to apologise for the missed diagnoses! Previously, that would have happened within 24-48h, but the NHS is in a very sorry state now.
Fortunately, the delay is unlikely to have compromised your recovery.
It’s not too surprising that your insurance company will proceed with you claim, since they are not likely to be called upon to make any payment and they will be able to charge the other company for their time!
Hope you’re on the mend and you receive some better news soon!
