Customizable action list

[jeffw16]

Closes #14

[Copilot]

Pull request overview

Adds a new configuration option to make which action= requests are blocked for anonymous users configurable, replacing the previously hardcoded action=history restriction.

Changes:

• Add CrawlerProtectedActions config (default ["history"]) and bump extension version to 1.3.0.
• Update CrawlerProtectionService::checkPerformAction() to consult the configured protected actions via a new isProtectedAction() helper.
• Extend unit tests to cover configured actions, empty configuration, and case-insensitive matching.
