fix(dashboard): properly filter dropdown menu buttons based on pre-hidden visibility

- Store button visibility state before hiding them in overflow/compact modes
- Use stored wasVisible data attribute to filter which buttons to show
- Prevents hidden buttons (like Done) from appearing inappropriately
- Also prevents visible buttons from being excluded when they're hidden by overflow manager
- Full mode now checks inline style to respect template display:none
