unfortunately, without a site visit, not one of us is likely to state categorically that it is safe.
however, with the switch replaced and the circuit having been moved to an rcd protected side of the board, your safety levels have increased dramatically.
I would prefer it to be a plastic light switch and i am a bit disappointed that the electrician did not verify that the earth to that point was sound.
Just Because someone has "fixed the problem" does not mean that it is safe. Although it SHOULD DO
I am still sceptical about the earthing to that switch, if it was correctly earthed then a short from live to earth should have caused the breaker to trip.
you have stated that the back box appears to be earthed correctly and there was no connection to the earth terminal of the switch itself.
generally the switch face, being metal is bonded to earth through the screws to the back box.
a short fly lead never does any harm, connected between the box and the switch earth terminal, however it is not strictly required if the switch is well made and screwed to a metal back box.
If it had been myself doing the work, I would have provided an invoice, detailing what the fault was, what the investigation found and what had been done to rectify it.
again, that is not strictly required but it provides the customer with some information and protects me from some possibly false claims when the washing machine or x box decides to fail shortly after my visit!!
I would advise a member of my family in your position to call a different electrician in the near future to come in and change the switch when the new one arrives.
or possibly calling the original one and asking them for the paperwork to prove that the circuit in question is safe.
I would be expecting a minor works certificate for the job and specifically asking for earth loop impedance to be detailed on the paperwork for both the light itself and the switch.
this might seem like a lot to take in, the electrician may have done these tests already when they came to fix the fault but if they have provided you with no paperwork to confirm this, how can you be certain?
If you want to direct them to this post on this forum, they can of course join in the conversation and may well be able to confirm that the relevant checks have been done.

Hi everyone, Not an electrician myself, but seeking knowledge, a second opinion and/or advice on the necessity to take action. Hope this is the right forum - please forgive me if not. We had a big fright today. Post refurbishment work, we put a kettle on in the kitchen and didn't realise it...
