feat: ensure prefix tag always display in createLogger

[vctqs1]

Description

Fixes #17604

The changes include:

• Moved the tag assignment outside of the if (options.timestamp) block for better clarity.
• Ensured that the tag is always included in the log message, regardless of whether a timestamp is present.

For now, when logging without timestamp=true

const logger = createLogger('info', {
  prefix: '[prefix]'
})

logger.info('message', { timestamp: false })

The prefix tag was not shown. This update ensures the prefix tag is always displayed.

@patak-dev the CI is passed now, could you help review this PR again

[patak-dev]

We use the logger with a vite prefix for normal messages. We can't do this change or we will break the CLI output. With this PR, this is how running pnpm run dev would look like:

The tag is intended to be used only to help while debugging, and as part of a timestamped message.
