Manage Domain Blacklist

[Nathans-mind]

Implementation:
A text field could be used where domains are separated by commas (e.g., example.com, anotherdomain.com), allowing users to quickly add or remove domains.

Alternatively, a UI element array (e.g., a list of domains with edit buttons) could be used to manage the blacklisted domains more dynamically.

Acceptance Criteria:
A UI component that displays the list of blacklisted domains.
Users can easily add and remove domains from the blacklist.
