Add URL double-click action option to Settings

[juzu-o]

Description

This pull request adds an option in Application Settings to configure the double-click action for the URL field in the entry view. Instead of the previous "Open browser on double clicking URL field in entry view" checkbox, there is now a dropdown selector allowing users to choose the desired double-click action for the URL field:

• Open in browser (default, preserves previous behavior)
• Edit entry
• Copy entry URL to clipboard (new)

This brings the URL field in line with the double-click behavior already available for username and password fields, allowing for a more consistent and customizable user experience.

Code changes include:

• Replaced the Open browser on double clicking URL field in entry view checkbox in the Settings dialog with a dropdown menu to select the double-click action for the URL field.
• Updated the settings UI and logic to support the new dropdown and persist the chosen option.
• Refactored the double-click event handler for the URL field to perform the selected action.
• Maintained backwards compatibility: the default is "Open in browser", so previous configurations are preserved unless the user changes the setting.
• Updated relevant settings serialization, tests, and UI strings.

The feature was originally requested in #4717

• [nitpick] Variable names 'oldConfig' and 'oldConfig2' are not descriptive. Consider using names like 'configWithOpenUrlTrue' and 'configWithOpenUrlFalse' to better indicate the test scenario.

The break statement after the switch block is unreachable because all switch cases already contain break statements. This creates dead code.
