Subject: [PATCH] Fix view field updates not persisting (#16672)

Fixes an issue where column width changes and other view field
modifications were not persisted, and a toast error was shown.

**Root Causes:**
1. Frontend was using client-generated IDs instead of database IDs for
updates
2. Backend cache was stale, causing `View field to update not found`
error

**Changes:**
- Use the existing database ID when updating view fields
- Exclude client-generated IDs when creating new view fields
- Invalidate flat entity maps cache before/after view field operations
- Refresh both view and view field caches to prevent validation errors

Fixes #16417
Closes #16381
