This commit aims at removing unuseful help message to:
1/ reduce translators work, to focus on more useful translations
2/ not sending unuseful information in load_views
3/ reduce help message to useful messages, so that we can mark
fields having a tooltip in the future UI.
4/ some cleanup of existing messages too
The main use cases:
- REMOVED: help redundant with the field name, providing no extra info
- MOVED TO COMMENT: technical help messages, that should not be in UX
