fix: increase FileField maximum length to 380 characters (#5390)

### 📣 Summary
Increased the maximum length of FileField models from the default to 380
characters.



### 📖 Description
The maximum length for FileField objects has been increased to 380
characters (100 by default). This change allows longer file paths to be
stored, ensuring compatibility with deeply nested directories or longer
file names that might have been truncated previously.
