Describe the bug

There was version update of DNS challenge provider Websupport.
This has changed the name of the plugin and variables holding the API keys and secret. #3513
But it seems that NPM doesn't adjust existing working configuration so the names match, therefore I cannot move forward with upgrade through 2.11.2 up towards latest version - because Admin UI doesn't work properly. Note that proxy hosts still somehow work - NPM forwards traffic.
I also installed clean 2.11.1 -> setup DNS websupport to get cert -> upgrade 2.11.2 - doesn't work -> upgrade to :latest tag -> still doesn't work.

Accessing admin page directly gives 404 error.
Through set-up proxy host (already done in advance) I get login page, clicking Sign in does nothing - in dev tools/network there's 502 for https://npm.xxxxx.sk/api/tokens.

Websupport DNS challenge was working fine for me in 2.9.19, it still renewed wildcard certificate 26th of November (few days ago).

Nginx Proxy Manager Version

Issue is happening at minimum from 2.11.2 and 2.11.3, also in :latest / 2.12.1

To Reproduce
Steps to reproduce the behavior:

1. Have working DNS challenge via certbot plugin websupport in 2.11.1 or older version
2. Upgrade to 2.11.2 or later
3. In console there should be errors that plugin cannot be found, adminUI won't work properly.

Expected behavior
Upgrading towards :latest or :2.11.2 will still find websupport DNS certbot plugin, admin UI works.

Screenshots

Screenshot shows working DNS challenge from Websupport in 2.11.1.
2nd half shows updated to 2.12.1 (current :latest) and login to admin UI doesn't work.
Forwarding (proxy hosts) are working.

Operating System

Debian 12 amd64 in a VM/VPS in some hosting provider. Using built-in SQlite, no external database.

Additional context

Docker 27.3.1, Portainer for container management/orchestration. Using docker compose/stack in Portainer to run NPM.
Stack was created around May 2022 when 2.9.19 was new. I've found this issue as I planned to upgrade in steps, checking if things still work.

For the upgrade testing I've created 2nd stack with different listening ports, same version 2.9.19, copied everything from "prod" to my testing env.
Then upgraded, started NPM, waited a minute till console is quiet to be sure all processes (perhaps migrations?) are done, and checked if proxy hosts and admin UI are working.
First smaller steps as I've seen some warnings in release notes.
2.9.19 -> 2.9.20 -> 2.9.21 -> 2.9.22 (latest 2.9.x)
Then decided to take latest from 2.10 as probaby more bugs are fixed, so
2.10.4
And then went to 2.11.3 which was too much and websupport plugin cannot be found and NPM has troubles.

What I also tried:
Stop container, go to docker volumes
In npm-letsencrypt/renewals/npm-10.conf i've changed:
-authenticator = dns-websupportsk
+authenticator = dns-websupport
In npm-letsencrypt/credentials/credentials-10 i've changed the plugin prefixes:
-dns_websupportsk_api_key = xxxxxx
+dns_websupport_identifier = xxxxxx
-dns_websupportsk_secret = xxxxxx
+dns_websupport_secret_key = xxxxxxx

But it didn't help, still same error.
I suspect that this data is in the SQlite database, however I didn't tried editing it.

I can change the version in docker compose back to 2.11.1 and NPM works, moving forward to 2.11.2 has these issues again. So I suspect old configuration is not migrated to new naming.

I've just tried also installing fresh 2.11.1 install in a vm, setup DNS challenge with websupport, successfully got certificate, served by NPM. Now stopped container, changed version to 2.11.2.
Now issue appears:

Start with the certbot path at /app/lib/certbot.js and reproduce an upgrade from 2.11.1 to 2.11.2 using an existing Websupport DNS challenge configuration. Trace how the stored configuration becomes the credentials file and how migrations are applied. Done means the existing Websupport configuration uses the current plugin naming, the admin UI works, and certificate renewal succeeds after upgrading.
