[Feature] FOMC Documents With Workspace Multi-File Viewer Widget

[deeleeramone]

1. Why?:

   • This adds requested functionality for cataloging and serving current and historical FOMC minutes and other documents.

2. What?:

   • Adds new endpoint with no standard model:
     • obb.economy.fomc_documents
       • Provider: federal_reserve
   • Historical documents from 1959 to 2024 are stored in a static JSON file, new items are read from items posted to the FOMC calendar on the Federal Reserve website.
   • Supplying a URL overrides other parameters to download the file directly.
     • A PDF file will return as a base64-encoded string.
     • Other files are returned, "as-is".
   • Endpoint is configured to produce a multi-file PDF viewer in Workspace.
     • This requires [Feature] openbb-platform-api - Create Entry In widgets.json For Forms #7055 to run openbb-api

3. Impact:

This function is anti-pattern for a few reasons.

Response is not an OBBject

• When no parameters are supplied, all historical and current documents are returned as a list[dict[str, str]] with keys:
  • date
  • doc_type
  • doc_format
  • url

In [3]: obb.economy.fomc_documents()[0]
Out[3]: 
{'date': '2025-01-29',
 'doc_type': 'monetary_policy',
 'doc_format': 'pdf',
 'url': 'https://www.federalreserve.gov/monetarypolicy/files/monetary20250129a1.pdf'}

• When a URL is supplied, all other parameters are ignored. A dict[str, Any] is returned with keys:
  • filename
  • content
  • data_format

In [4]: obb.economy.fomc_documents(url='https://www.federalreserve.gov/monetarypolicy/files/monetary20250129a1.pdf').keys()
Out[4]: dict_keys(['filename', 'content', 'data_format'])

In [5]: obb.economy.fomc_documents(url='https://www.federalreserve.gov/monetarypolicy/files/monetary20250129a1.pdf')["data_format"]
Out[5]: {'data_type': 'pdf', 'filename': 'monetary20250129a1.pdf'}

• When, as_choices = True, an array compatible with Workspace Params Options is returned.

In [6]: obb.economy.fomc_documents(year=2025, as_choices=True, pdf_only=True)
Out[6]: 
[{'label': 'Monetary Policy - 2025-01-29',
  'value': 'https://www.federalreserve.gov/monetarypolicy/files/monetary20250129a1.pdf'},
 {'label': 'Minutes - 2025-01-29',
  'value': 'https://www.federalreserve.gov/monetarypolicy/files/fomcminutes20250129.pdf'}]

CLI has no adapter for this type of scenario.

• CLI has been modified to handle the base, no parameters scenario.
• The url param is not compatible with the command execution because of slashes.

4. Testing Done:

   • Unit and integration tests, modified to accommodate not returning OBBject.
   • CLI scenarios.
