feat: add "URL Does Not Contain" condition to rule engine (#2280)

* feat: add "URL Does Not Contain" condition to rule engine

Add a new condition type `urlDoesNotContain` that allows users to create
rules based on URLs that do NOT contain specific strings. This enables
more flexible rule configurations, such as:

- Automatically adding bookmarks to a "Read Later" list if the URL
  does not contain "reddit.com" or "youtube.com"

Changes:
- Added `urlDoesNotContain` condition type to Zod schema
- Implemented evaluation logic in RuleEngine
- Added UI support in ConditionBuilder component
- Added translation key for new condition type
- Added test coverage for the new condition

Fixes #2259
