Docs : Add notes support to Company API endpoints

[markdennis22]

Summary from Issue : 433712

This PR combines the changes from #311 and adds the GET endpoint for company notes:

• Added notes field to all company API endpoint responses
• Added company_note and company_note_list schemas
• Added new GET endpoint /companies/{id}/notes to retrieve all notes associated with a company

Changes from PR #434391

• Updated PUT /companies/{id} endpoint to include notes in response
• Updated GET /companies endpoint to include notes in response
• Updated POST /companies/list endpoint to include notes in response
• Updated GET /companies/scroll endpoint to include notes in response
• Updated POST /contacts/{id}/companies endpoint to include notes in response

Changes from PR #434807

• Added GET /companies/{id}/notes endpoint definition in the OpenAPI spec
• Created company_note_list schema for paginated company notes responses
• Included proper error handling for when a company is not found (404 response)

Notes Field Structure

The notes field follows the same pattern as contact_notes:

• type: "note.list"
• data: Array of addressable_list items representing note references
• url: URL to fetch all notes for the company
• total_count: Total number of notes
• has_more: Pagination indicator

Test plan

• Verify the OpenAPI spec validates correctly
• Test that company endpoints return notes field correctly
• Test the new GET /companies/{id}/notes endpoint returns notes for valid company IDs
• Verify 404 response for invalid company IDs
• Ensure pagination works as expected
