The sign seems to be telling any tram coming down Canning Road that it is
allowed to turn left, but there have never been any tram tracks in Canning
Road. Is this just a mistake, or is there some legal reason for that tram
sign being there?

It isn't telling non-existing trams to turn left because it isn't a
'direction sign' for approaching vehicles. The white on blue colour code of
the sign tells you that it is an 'advance information sign' describing the
restrictions in the street beyond the junction. Think of it as information
'about trams' not 'for trams'.

It's basic highway code stuff this, it's the type of sign on page 7 he

Your second example is similarly not giving direction information to trams,
it is advising all users of a timed restriction due to trams. I can't
really see an issue with it.

Your third example is probably just belt and braces - as IIRC in normal
circumstances emergency vehicles might often go through a no-entry sign to
overtake slow moving queues - perhaps not a good idea here...
