feat: keyboard paste at pointer position

[Kneemund]

Makes content pasted using CTRL + V appear at the cursor location instead of the top left corner of the page. Falls back to the previous behavior if the cursor is outside of the canvas.

• Fixes Pasted content always appears in the top-left corner instead of at the cursor position #1304.

I get the following error when compiling the project with this commit. Am I doing something wrong?

Are you sure that you applied the commit correctly? You need to add use rnote_engine::ext::GraphenePointExt; according to the error message, but the commit already adds that.

[tunjan]

Yes, that was the issue. Thank you, it works as expected.

* Fixes [Pasted content always appears in the top-left corner instead of at the cursor position #1304](https://github.com/flxzt/rnote/issues/1304).

I don't want to sound impatient. But what should we do before this pull request gets merged into the main branch?

[flxzt]

looks good, thanks @Kneemund !
