docs(manage-files): add client init block before Python SDK examples

[glody]

Summary

Most Python SDK snippets on docs/get-started/concepts/manage-files.mdx use client.files.... without any prior client = NeMoPlatform(...) construction. Copy-pasting any of them into a fresh interpreter raises:

NameError: name 'client' is not defined

The nightly NMP_Docs_Review build flags this as a high-severity snippet defect on every run.

Follow the pattern used on the Manage Secrets page: place the standard initialization block at the top of the Python SDK examples section (right after the "Managing Filesets" H2's CLI tip), so readers landing on the anchor can copy any subsequent snippet with confidence.

Existing per-snippet init blocks (Creating Filesets, RichProgressCallback, S3 credential chain, etc.) are left intact — they're standalone snippets that legitimately re-declare setup.

Diff (added block)

import os

from nemo_platform import NeMoPlatform

client = NeMoPlatform(
    base_url=os.environ.get("NMP_BASE_URL", "http://localhost:8080"),
    workspace="default",
)

Test plan

• fern build renders the added block.
• Nightly docs-review no longer flags snippet: client on get-started/core-concepts/manage-files.

Summary by CodeRabbit

• Documentation
  • Added a Python SDK client initialization example to the file management guide.
  • Documented configurable base URL and default workspace settings, including a localhost fallback.

File Management Documentation

Layer / File(s)	Summary
SDK client setup example docs/get-started/concepts/manage-files.mdx	Added a reusable NeMoPlatform initialization example with an NMP_BASE_URL setting, a localhost fallback, and the default workspace.

Suggested reviewers: a2bondar

Merge Risk: 🔵 Low · up to 8415a

The new initialization block makes the Python examples copyable, but an explicitly empty NMP_BASE_URL bypasses the localhost fallback and can cause those examples to fail; merge is reasonable with owner awareness or a follow-up adjustment.
