Improve UX of the paste special fallback dialog

[vmiklos]

Describe the Bug

In case navigator.clipboard.read() fails for paste special, then we show a dialog which does work, but it has poor UX and can easily confuse users.

Steps to Reproduce

1. Open Calc
2. Copy a cell
3. Click the paste dropdown on the notebookbar
4. Click the paste special menu item

Expected Behavior

A clear dialog that explains it's time to press Ctrl-V.

Actual Behavior

A dialog that looks like just a warning to be ignored, and a confused user when pressing OK doesn't result in a paste special.

Screenshots

Desktop

Tested on Linux with Firefox, Chrome doesn't show this dialog anymore (with experimental settings enabled).

Suggested fixes

1. 'Ok' legend needs renaming to 'Cancel' in 23.05 - no translation change needed and 'Cancel paste special' in 24.04
2. We should bold the 'Please press now:' - which at least in English should say: "Please press" so it is far more visible.
3. We should loose the excessive white-space at the bottom of the dialog if we can.
4. Probably we should have a "Paste from this document" button as well which is likely the majority use-case and shouldn't need access to the clipboard

Yep, full agree!

I think it could just be reworded to:

Your browser has very limited access to the keyboard.

Press Ctrl + V to see more options.

Then you would just naturally:

• Press Cancel (or click out of popup) if you want to get out.
• Press Ctrl+V if you want to go further.
  • Bringing you to the "Paste Special" dialog.

Also maybe:

• Center+Bold the first line / warning.

I think that'll make it easier to understand the popup. :)

Side Note: I just wrote a little about the clunky Calc "Paste Special" dialog here too:

• Use also Ctrl or Alt when dragging rows, columns, cells #8033 (comment)

The above two PRs are now in, closing.
