The --dbpath option is bad. Despite its name, it is not a "path", but a
prefix. The sa-update man page states it is in bayes_path form, which is
documented in the general SA Conf documentation.
"This is the directory and filename for Bayes databases". Since your
given path looks similar to the default, I assume you actually meant to
keep that SA data in the .spamassassin/ dir. For that, just drop the
trailing slash. Also, please re-read carefully that part of the docs.

This is dangerous. With lots of mail in the (Maildir?) folder, shell
expansion *quickly* will exceed the command line length limit.
I believe passing the Maildir directory containing the messages should
do. Someone who actually uses sa-learn with Maildir please correct
me. :)
The trailing dot also looks bad.

That is OK. As has been answered already, SA will not learn a given
message twice, the same type. It will, however, re-learn and revert the
previous learning, if you later correct the type and learn as something
different.
Please do read the sa-learn man page.

A word of caution. There is no move command with IMAP. Instead, it is
copy and delete. Or rather mark-for-deletion, since there is no delete
command either. That's expunge.
In practice that means, that a mail that supposedly has been "moved" to
e.g. a junk folder, *still* is in its source folder, marked for
deletion, usually not visible to the user -- until that folder has been
expunged. Training Bayes from that folder will also learn from these
invisible, "deleted" messages.
Using the Inbox rather than a dedicated ham folder therefore is NOT a
good idea.
