This update addresses a bypass that allowed scammers to bypass C2
detection by using alternative network request types to communicate with
their Command and Control (C2) servers. Previously, we only listened for
a limited set of request types (e.g., main_frame, sub_frame,
xmlhttprequest), which left the system exposed to other methods of
calling C2s.

With this fix, we now listen to all network request types and
cross-check them against our client-side blocklist, ensuring better
coverage and preventing these types of bypasses.

Changes:

Updated maybeDetectPhishing in background.js to listen for all network
requests by removing restrictions on request types.
