refactor: migration validation

[larskemper]

Changes

General

• unified logging and exception handling (own validation exception class)
• split invalid field value in required / optional field log (required is an error, optional a warning)
• added translation log for future fix implementation
• fix conversion of order custom fields (before was set to invalid "null" if not existing)
• fix sizing and coloring of ssl url in ui
• fix unpinned padding of log group table

Validation wise

• added check for database field definition: field now get marked as required if: definition has required flag, database field is not nullable and has no default value
• removed check for unexpected fields (adds unnecessary noise to logs and errors)
• removed db lookup of associations ids (n+1 query problem)
• removed validation of association fields by serializer (often false positive, cause of missing write context data)
• added a more naive / basic check for association fields: correct data structure and valid ids
