Requested after a live failure: pasting into the hidden Application Key
field silently captured nothing (terminal/SSH-client dependent), and the
only symptom was a generic "one or more fields left blank" warning after
all four prompts had already gone by — no way to tell which field, or
even that the paste itself was the problem rather than something else.
Each of the four fields now echoes its character count right after entry
(never the value for the hidden Application Key field, just its length),
so a failed paste is visible immediately instead of discovered several
prompts later. The blank-field warning now also names exactly which
field(s) were empty instead of a generic message.
Verified against the user's actual reported case: bucket/endpoint/key-ID
entered normally, Application Key came back empty — reproduces as
"(0 characters entered)" on that line and "Left blank: Application Key"
in the warning, both confirmed against a second case where all four
fields are present and it passes through cleanly.
