* Update csv parser on sales

# Context
- https://digital.dclg.gov.uk/jira/browse/CLDC-2344
- So the reported bug and these change do not match 100%
- As the reported bug should have already been resolved in an earlier change as the error message that was reported has already been removed from the system
- These changes remove the check from sales plus a few minor tidy ups
# Changes
- Remove dead code around error threshold which is no longer used or needed
- Inverted negative predicate to positive one, `incorrect_field_count` => `correct_field_count`
- Remove `validate_min_columns` from sales bulk upload
* refactor questions from validator to row parser
* able to switch between bulk upload parsers
- depending on what year we are processing
* spec tooling to support bulk upload multi year
* row parser now has year in namespacing
* add static data for 2023 row parser
* add placeholder to log to csv for specs
* bulk upload aribtrary 23/34 column ordering works
* bulk upload supports 23/24 without headers
* bulk upload 23/24 supports BOM + invalid chars
* dupe tests
* port 23/24 attributes_for_log
* port 23/24 bulk upload validations
* force crossover period
* tweak max permitted columns
* able to return column for given field
* work out column for field for errors
* add field_4 as 23/24 setup field
* remove duplicate method
* map schemes and locations correctly
* handle arbitrary number of header rows
* add missing fields to bulk upload support
* fix bulk upload age data types
* bulk upload handles both with and without headers

* add class to create logs from bulk upload
* create logs when processing bulk uploads
* remove bulk_upload_id from csv output
* create bulk upload logs only if all valid
- this will be changed later to allow for partial logs
- and only to create logs when a threshold has been met
* add method to blank invalid non setup fields
* bulk upload log creation blanks invalid fields
* fix incorrect logic for bulk upload renewal
* fix linting
* bulk upload log creation fail logs to sentry
* fix bulk upload line ending parsing
