[Technical debt] Migration to ng-icons

[cmoinier]

Description

This PR migrates all apps icons from mat-icon to ng-icon (and various fixes found along the way).

Notes :

• All icons except for the editor's are still based on Google material, exceptionally on tabler-icons, which were better suited on some occasions.
• To fit the mockups, the editor icons are based on Iconoir.
• For "conditional icons" (eg : icon names passed as inputs into a component), the icon in question must be imported in the module / component where it's rendered.
• Added missing translations
• Fixed record preview feed story
• Removed import.cy e2e file because its tests belong in the record-actions e2e file.

Architectural changes

Added the ng-icons library, as well as "ng-icons/material-icons", "ng-icons/tabler-icons", and "ng-icons/iconoir".

Thank you!! very impressive work!! I've tested several pages randomly and couldn't find any issues. I wrote down a few remarks in the code, I feel like this PR highlights very much the need for us to have exclusively standalone components, since importing icons becomes very cumbersome otherwise.

Also I think there's a new mat-icon that snuck in there since the branch was rebased on main :)

I'm looking at the test failures now, it seems like a very deep issue, will report there if I find something
