Hi again David, & thank you. It was all getting too hard, so after reading your latest reply, i chose to deploy your earlier "nuclear option: delete your ~/.local/share/kwalletd". Being a coward, i didn't actually delete it, but renamed it so it would no longer be active, then observed in Dolphin as Plasma instantly created a new virgin version. I rebooted, logged in again, sequentially launched my chromium-based browsers & went to a page for which i need to sign-in, saw that these browsers were added to my new wallet, launched my VPN via Network Manager & ditto observed it added to wallet again. Now for the test; i logged out & in again.
Good news: now, finally, i could successfully reconnect to my VPN trouble-free. Before trying, i did observe that wallet was still open, ie, it had survived the logout/in.
