This commit adds a missing handler for the captcha state. This uses the checkouts handle request captcha method to request a captcha and wait for the token. The handler has also been updated to include error checking.

This commit adds a protocol interceptor to load our captcha html instead of the regular html for other sites.

This commit also updates the captcha server middleware stack to better handle loading assets such as images/styling/js while still redirecting everything else to the captcha html page.

Issue: #204

Some sites include unsupported size option values, which affects our variant group matching. This commit adds a temporary workaround until the actual issue (#239) is addressed.

Additionally, a linter error is fixed, some unnecessary log statements are removed, and another log statement is adjusted to only display relevant information.

This commit addresses some (not all!) captcha related bugs:
- Captcha Window Reloads are now handled properly
- Redundant Captcha Reset calls are removed
- Captcha Windows don't get reset in the middle of harvesting
- Attempting to add >5 captcha windows no longer crashes the frontend

These are some small bugs that fall under the scope of this branch. Other larger bugs that require separate issues are not fixed in this commit.
