#11518 Fix/invoices more actions dropdown

Improve the "More actions" menu on the Invoices page

What changed

A cleaner menu

• The ⋮ button's menu now looks like a proper menu instead of a stack of separate buttons.
• It has a small "Actions" title at the top.
• Each action is a simple row with an icon and a label, highlighted when you hover over it.
• The text and icons are smaller, matching the rest of the page.
• "Delete" sits at the bottom, separated by a line and shown in red.

Easier to close

• There is a new close (✕) button in the top corner.
• Clicking anywhere outside the menu now closes it.
• Choosing an action closes the menu, as before.
• Clicking a greyed-out action no longer closes the menu by mistake.

A better-looking ⋮ button

• The ⋮ button now matches the other toolbar buttons on the dark theme instead of standing out.

How to test

1. Go to Accounting → Invoices and select an invoice.
2. Click the ⋮ button next to the delete button.
3. Check the menu looks right on both the dark and light themes.
4. Close it with the ✕, by clicking outside it, and by choosing an action.
