fix(#10357): prevent DEBUG logs from appearing in production

[sugat009]

Summary

Fixes #10357 - DEBUG logs were appearing in production despite NODE_ENV=production.

Changes:

• Default LOG_LEVEL to 'info' when not explicitly set in application code
• Add LOG_LEVEL: 'debug' to CI workflow env (instead of repeating in each npm script)
• Fix sentinel helm template to use .Values.sentinel.log_level instead of .Values.api.log_level
• Add sentinel.log_level and api.log_level defaults to base.yaml

Based on

This PR is based on the work by @AmirSaudagar55 in #10376. Additional fixes were made to:

• Resolve merge conflicts with master
• Fix helm template values path for sentinel
• Refactor LOG_LEVEL=debug from npm scripts to CI workflow env

Code review checklist

• UI/UX backwards compatible: Test it works for the new design (enabled by default). And test it works in the old design, enable can_view_old_navigation permission to see the old design. Test it has appropriate design for RTL languages.
• Readable: Concise, well named, follows the style guide, documented if necessary.
• Documented: Configuration and user documentation on cht-docs
• Tested: Unit and/or e2e where appropriate
• Internationalised: All user facing text
• Backwards compatible: Works with existing data and configuration or includes a migration. Any breaking changes documented in the release notes.

@jkuester Would appreciate a review on this. Thanks!

Thanks for keeping this going! Just a couple minor things and this should be good to go!

Can we also get a docs PR to update the log level documentation?

Another thing that is worth considering is if we should update the dev-api and dev-sentiel commands to set LOG_LEVEL=DEBUG? I think we want the debug logs when running in the development environment...

Actually, there is already a PR for this. medic/cht-docs#2030

Gotta question about the extra compose file!

A couple minor suggestions around not reading the host LOG_LEVEL envar even for our test/development scripts. I am fine if you want to keep them as-is, but I just think it will be less complex to just hardcode the value (and might save some confusion in the future).
