## Why
After the changes on relations, index on relations were skipped by the
syncmetadata service, so no more migrations were generated for relation
fields.
We wanted to fix this.
## Test
This PR adds unit tests for the `createIndexMigration` utility in the
workspace migration builder. The tests cover:
- Creating index migrations for simple fields (e.g., text fields)
- Creating index migrations for relation fields (ensuring correct column
naming, e.g., `authorId` for the `author` objectmetadataname)
## Excluded
The delete index on relation does not need the column names so i don't
think i needed to work on this method. I might be wrong.
## Checklist
- [x] Added/updated unit tests for index migration creation
- [x] Verified correct handling of simple and relation fields
- [x] Ensured all tests pass

This PR is dropping the column `targetColumnMap` of fieldMetadata
entities.
The goal of this column was to properly map field to their respecting
column in the table.
We decide to drop it and instead compute the column name on the fly when
we need it, as it's more easier to support.
Some parts of the code has been refactored to try making implementation
of composite type more easier to understand and maintain.
Fix#3760
