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 π)
- maybe more changes I forgot I've done πCloses#24893

Ran most of the Less files through the Less compiler and Prettier and
then followed up with a round of manual fixes.
The Less compiler had unfortunately stripped all `//` style comments
that I had to restore (It did preserve `/* */` comments). Other fixes
include duplicate selector removal which were revealed after the
transpilation and which weren't caught by stylelint before but now are.
