Describe the bug
oneuptime helmchart install or upgrade fails when using external clickhouse with the error:

Error: failed to create resource: Secret in version "v1" cannot be handled as a Secret: illegal base64 data at input byte 8\n'

Im suspecting the password field to be the culprit for this, If i re enable the clickhouse the deployment is successful.

To Reproduce
Steps to reproduce the behavior:

Deploy helm chart the usual way
set clickhouse.enabled=false
populate the externalClickhouse values

Expected behavior
Helm chart deployment should proceed and use external clickhouse instead of creating a new clickhouse pods.

Screenshots

Desktop (please complete the following information):

OS: linux
Version: latest helmchart

Smartphone (please complete the following information):

Device: [e.g. iPhone6]
OS: [e.g. iOS8.1]
Browser [e.g. stock browser, safari]
Version [e.g. 22]

Deployment Type
Is this issue on SaaS (at https://oneuptime.com) or self hosted (the version that you deployed on your server)?
