As discussed in #31667 & #26561, when a card on a Project contains
images, they can overflow the card on its containing column. This aims
to fix this issue via snapping scrollbars.
---
Issue #31667 is open to discussion as there should be room for
improvement.
Fixes https://github.com/go-gitea/gitea/issues/30682 and does a few
improvements:
- Use gap instead of margin/padding
- Don't render empty image div
- Remove `right floated` class that did nothing

1. Add "grabbing" cursor while dragging items:

2. Make project board only drag via their header, not via their whole
body.

3. Fix some cursor problems in projects
4. Move shared options into `createSortable`.
I propose to decrease font size. 18 is too big and looks ugly, on
windows. 14 is on par with other elements and save a bit of space.

This PR refactors a bunch of projects-related code, mostly the
templates.
The following things were done:
- rename boards to columns in frontend code
- use the new `ctx.Locale.Tr` method
- cleanup template, remove useless newlines, classes, comments
- merge org-/user and repo level project template together
- move "new column" button into project toolbar
- move issue card (shared by projects and pinned issues) to shared
template, remove useless duplicated styles
- add search function to projects (to make the layout more similar to
milestones list where it is inherited from 😆)
- maybe more changes I forgot I've done 😆Closes#24893
After:
