[Feature Request] Use global search for current list and include list actions

[KodeBarista]

Issue/Description
Currently, each task list includes its own search icon, while the application already provides a global search bar. This results in duplicate search functionality. Instead, when viewing a task list, the global search bar should search only within the currently opened list. This would provide a consistent search experience across the application.

Additionally, the search icon space can be utilized by showing a vertical ellipsis menu containing actions specific to the current list, such as:

• Rename
• Set icon
• Export
• Delete

Expected Behavior

• The global search bar searches only the currently opened task list (similar to Files).
• Replace the list search icon with a vertical ellipsis menu in task list page.
