Are there any reliable online sources for the dates of individual world championship games? (I'm taking it that chessgames.com, while invaluable in its way, is not such a source.)

You could download and install the free demo CBLight 2009. This gives access to the ChessBase online database. A quick check against the 1972 match indicated that the dates quoted look reliable. Memo to chessgames.com - the 1972 match was played in the summer, not in January.

It looks as if ChessBase have updated their data with dates when readily available. Those with memories of the *.CBF and *.CBI formats will recall that you could only input the year of the game.
