feat(send-to-caas): support CTA URL localization via caasLocaleInject metadata flag

[sanrai]

Description

This change adds the ability to automatically prepend the page's locale segment to primary and secondary CTA URLs when a page is localized, controlled by a new metadata flag.

Previously, localization logic was missed in the post-processing step in getCaaSMetadata(). We've refactored it so the locale injection is scoped entirely to the CTA URL computations in send-utils.js, making the metadata builder itself simpler and preserving its original responsibility.

Resolves: MWPW-167994

What's Changed

• Introduce localizeCtaUrl(val) helper (in tools/send-to-caas/send-utils.js)
  • Reads <meta name="caaslocaleinject" content="true"> (case‐sensitive)
  • Uses getPageLocale(window.location.pathname) to detect if the page is localized
  • Wraps the output of checkCtaUrl(...) for both cta1url and cta2url
  • Prepends /${locale} to the URL path only once, if not already localized
• Refactored props.cta1url and props.cta2url to call localizeCtaUrl(checkCtaUrl(...))
• Simplified path logic to a single assignment, since URL.pathname always begins with "/"
• Ensured the metadata flag value is lowercased when read, matching how the backend emits it

Why

• Encapsulates locale injection solely at the CTA prop level, keeping the core CaaS metadata builder untouched
• Improves code clarity and maintainability by localizing complexity to a single helper
• Honors pages that have not been localized (default/global pages remain unaffected unless the metadata flag is set)

To test

Author a word doc and put some already localized links and others not.

Toggle this caasLocaleInject parameter (either omit it for legacy consumers or let it be true for consumers who need this)

You will see the unlocalized link localized and the localized link stay the same.
