It depends on several things. You say you're using konsole, so does
that mean you're running KDE? If so, are you logging in via sddm,
which is what KDE on Debian normally uses? If all of those things are
true, then editing .profile probably doesn't do anything at all. An
sddm login running a Debian X11 session which runs KDE shouldn't
be reading the .profile file. Ever.
Are you logging in on a console and running startx? In that case,
your .profile *will* be read, by your console login shell, and the
changes to PATH and other environmental bits and bobs will all be
inherited by the X11 session, then by the window manager, then by
the terminals which are children of the window manager, and then by
the shell run inside the terminal, and then by the programs launched
by the shell.
If you aren't using startx from a console login, then the right place
to make modifications to PATH would be in the ~/.xsessionrc file.
I *just* got done saying all this stuff last week.
Now, your immediate question was how to make the PATH change take
effect in all of your existing terminal windows, without having to
log out and back in. There's no single command that'll just blast
it out to all of them. Each one is an independent self-contained
process, with its own separate copy of the environment. You'll
have to go around to each window, one by one.
The most straightforward way to do it would be to paste your PATH=...
command into each window.
If you don't like that approach, you could add your PATH=... to
your ~/.bashrc file (assuming you use bash) temporarily. Then in
each window, run "exec bash" to run a new shell, which will read
the ~/.bashrc file, which will pick up the PATH change. When all
of the windows have been re-shelled, you can edit ~/.bashrc again
to remove the PATH=... command, since you don't want it to stay there.
