Hidden fields

[dmpetrov]

Description

Users usually only need to see basic fields like path, size and etag when viewing File. We should hide other fields by default to reduce UI clutter, while keeping them accessible when needed.

We need a way to mark rarely used fields as "internal" in our data model.

Example:

class File(DataModel):
    """`DataModel` for reading binary files."""

    source: str = Field(default="", hidden=True)
    path: str
    size: int = Field(default=0)
    version: str = Field(default="", hidden=True)
    etag: str = Field(default="")

Note, it should be general approach. User should be able to have hidden fields in their classes.

Open question:

• Should size be hidden? Likely yes.
• etag should be visible (to emphasise the consistency and see changes). It looks like it needs to be moved next to path (before size and version).
