ILE (indefinite leave to enter) is given to people outside the UK. ILR (indefinite leave to remain) is given to people either at the point of entry to the UK or if their immigration status changes to indefinite leave while they are in the UK.
An ILE visa/entry clearance is normally has, I think, a six-month validity from the date of issue. This means that the holder can use it for six months to make his or her
first entry to the UK. On arrival in the UK, the holder is de facto given leave to remain in the UK for an indefinite period and the ILE visa itself becomes effectively irrelevant.
So the short answer to your question is that you don't do anything to change from ILE to ILR - it happened when your wife arrived in the UK (I am assuming that she did in fact make her first entry to the UK during the validity of the ILE visa and that she does indeed have leave to remain in the UK indefinitely). The important thing for the check-in people to understand and look for is the entry stamp(s), not the ILE visa.
It is surprising that the problem that you describe arose in Hong Kong, where check-in staff must see a lot of holders of UK ILR. If necessary you can ask to see the staff member's supervisor, although that really shouldn't have to be the case. If all else fails, I don't know if your wife can get the Home Office to write a letter confirming her immigration status - someone else might know the answer to that one(?).
