Add schema on read for parquet and json DFS sources, just like we do for CSV source.
We should also fix
S3EventsHoodieIncrSource
as well.

Research direction
Locate the CSV source's existing schema-on-read implementation and compare it with the parquet and JSON DFS sources. Then inspect S3EventsHoodieIncrSource, which the issue also calls out; the work is done when all named sources provide schema-on-read behavior consistently with CSV.
