ViewGroup and ViewFilters side effect in v2 (#15096)

# 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
