v3.32.7: drop the pySim JSON disclosure from the file manager

The decoded view is the client-side EF decoder's table over the raw
read's bytes.  The collapsed "pySim JSON (server)" block was an
unrelated second decode - opening it ran another /api/read with mode
'decoded' (pySim's read_binary_decoded/read_records_decoded on the
card) - and it existed only when our decoder covered the file, so it
could not serve as a cross-check where one would matter.

/api/read keeps mode 'decoded' for API callers.  Help, READMEs and the
project notes now state the table is built in the browser from the same
raw bytes; ef_decode.test.js pins the view's output and that no
mode 'decoded' read remains in the PWA.
