Subject: [PATCH 02/19] Feature/tech 8534 reorder master columns (#200)

* feat: reorder columns mapping

Grouped different columns into sections for easier mapping and UX

* feat: add descriptions for column mapping

Related to TECH-8531, adding more precise descriptions for column mapping, indicating some examples and their type.

* fix: css fix and db info for tooltip

have hardcoded data as fallback for first getting the information from the database

* feat: pin id and name to be first items

order as figma
