docs: tell users where to change the admin password after --reset

The Forgotten Passwords section explained how to run --reset and log in as
`admin` with the generated password, but never said where to change that
random password to a memorable one. Users reported hunting the menus with no
luck.

Add a "Change the Reset Password" step pointing to the Trust Profile page
(username menu, bottom-left) and link to afterInstall.md#set-a-password.
Constraints verified against notifiarr v0.9.5 (pkg/client/cli.go
resetAdminPassword + frontend profile page): reset generates a random `admin`
password; the Trust Profile page needs the current password and a new password
of at least 9 characters.

 !!! note "About Reset"
-    The `--reset` command creates a local admin password as a recovery fallback. This is only needed if you can't login with your Notifiarr.com credentials. After reset, you can login with username `admin` and the generated password, then set up your normal authentication.

 - If you still can't login, restart the container.
 
+### Change the Reset Password
+
+The generated `admin` password is random. Once you're logged in, change it to something you'll remember so you don't have to reset again:
+
+1. Click your username in the bottom-left of the Web UI menu.
+1. Open the *Trust Profile* page.
+1. Enter the current (reset) password, set a new password of at least 9 characters, and save. You can also configure an auth proxy header here instead.

+See [Set a password](afterInstall.md#set-a-password) for more detail.
