feat(mTLS): Client Certificate Handling in Extension + Popup Redirect Update

This PR introduces mutual TLS (mTLS) client-certificate handling inside the extension and updates the popup redirect URL.

---

Summary

• New: Detect and forward client certificate payloads from the web page → content script → background script.
• New: Background script validates and attempts delivery of the certificate to the browser via a custom Chrome API: chrome.wootz.mtlsCert.
• Update: popup.html redirect changed from http://eb.wootzapp.com/okta to http://trust.wootzapp.com/okta.

Changes

1) mTLS Certificate Handling

content.js

• Listens for the custom DOM event: okta-integrator-cert.
• Extracts event detail (certificate payload and optional metadata).
• Sends the payload to the background script via chrome.runtime.sendMessage.
• Adds defensive checks and console diagnostics for malformed events.

background.js

• Receives type: 'mtlsCert' messages from content.
• Validates presence/shape of certificate fields (e.g., PEM/DER, chain, fingerprint).
• Logs structured details (redacting sensitive material).
• Calls chrome.wootz.mtlsCert.send(...) (custom API) to forward the certificate to the browser for mTLS flows.
• Handles success/failure paths with detailed error logging and user-actionable hints.

2) Popup Redirect

popup.html

• Redirect target updated:
  • Old: http://eb.wootzapp.com/okta
  • New: http://trust.wootzapp.com/okta
