## Context
- All flatEntity should extend SyncableEntity
- SyncableEntity should now have applicationId and application relation
- Fix syncApp deletion, should now properly use migration v2 to delete
syncable entities
# Introduction
### Summary
Implements side effect handling for `ViewGroup` and `ViewFilters` when
field metadata is updated in the v2 architecture. This ensures that
view-related records are properly maintained when enum field options are
modified, deleted, or created.
### Side effects
- **Side Effect System**: Added side effect handling for field metadata
updates that manages related view groups and view filters
- **Enum Field Updates**: When enum field options are modified, the
system now:
- **View Groups**: Creates new groups for added options, updates
existing groups for modified options, and deletes groups for removed
options
- **View Filters**: Updates filter values to reflect option changes and
removes filters that reference deleted options
### Enum runner fix
Update now works for both atomic enum and array enum ( multi select for
instance )
### Compute flat entity maps from to
Standardized this method usage across v2 services
Next step is to require dependencies dynamically

# Introduction
Adding view-group to core engine v2
Following https://github.com/twentyhq/twenty/pull/15010 ( same pattern )
## What's done
- Created flat-view-group
- flat view group runner
- flat view group builder
- create view group service v2 and input transpilers
- refactor the existing view group resolver to fix standard (
BREAKING_CHANGE on graphql api update especially ) REST stays the same
- refactored the front to consume the mutations autogenerated
