Allow to delete startup entries altogether

**Problem**

Currently, startup entries can only be disabled, still cluttering the list.

**Solution**

I'd like to be able to conveniently delete the registry entry for a startup program altogether, cleaning up the list of startup program, and allowing to remove left-overs from programs that uninstalled unproperly.

**Alternatives considered**

Manually navigating to the registry key in order to delete it is inconvenient. I believe Tools like Glary Utilities allow to delete startup entries.

**Mockups / references**

Showing a trash bin icon next to the toggle / link button would be a nice UI.

**Additional context**
