chore: replace Task::perform with Task::done

[tvolk131]

For Tasks that have no async future/task that helps produce the final message (i.e. tasks of the form Task::perform(async {}, |_| { do_stuff() }), we can simplify to Task::done(do_stuff())

Pull Request Overview

This PR simplifies synchronous task creation by replacing Task::perform(async {}, |_| { message }) patterns with the more direct Task::done(message) for tasks that don't require any asynchronous computation.

• Replaces 31 instances of Task::perform(async {}, |_| { ... }) with Task::done(...)
• Maintains the same functionality while reducing code verbosity
• Focuses primarily on toast notification messages and simple state updates
