Migrate kafkajs to @confluentinc/kafka-javascript

[joebowbeer]

Closes #1191

Migration Guide: https://docs.confluent.io/kafka-clients/javascript/current/migration.html

I used the following commands to update the packages and lock:

nvm use 24
npm install -g npm@latest
npm install
npm audit fix
cd packages/modules/kafka
npm install -D @confluentinc/kafka-javascript
npm uninstall kafkajs
cd ../redpanda
npm install -D @confluentinc/kafka-javascript
npm uninstall kafkajs

Notes:

• I needed to install npm >= 11.6.3 to avoid adding extraneous 'peer: true' diffs to the package-lock
• I ran npm audit fix to address the high severity finding below

# npm audit report

jws  =4.0.0 || <3.2.3
Severity: high
auth0/node-jws Improperly Verifies HMAC Signature

fix available via `npm audit fix`

@cristianrgreco I addressed the three SASL_SSL test errors

This is ready to merge.

Btw, one of the unmodified tests fails for me locally in Rancher Desktop on Apple Silicon, as noted

This is because there's no arm64 image for the requested zookeeper image.

Thanks @joebowbeer! I'm a bit swamped at the moment, will look at it soon
