Submit individual Form 300/301 injury and illness case records via the OSHA ITA API

Steps

1. Log into OSHA's Injury Tracking Application (ITA) and retrieve your ITA API Token from the API Token page.
2. Add a case with `POST https://www.osha.gov/oshaApi/v1/forms/caseData`, header `Authorization: Bearer {ITA API Token}`, and a JSON body containing the embedded `establishment` (`id` or name) plus required case fields (`case_number`, `job_title`, `date_of_incident`, `incident_outcome`, `type_of_incident`, narrative fields like `nar_what_happened`, etc.); submit an array of case objects to add multiple cases at once.
3. Retrieve a single case by its generated `id` with `GET /oshaApi/v1/forms/caseData/{caseDataId}`, or list every case for a site with `GET /oshaApi/v1/forms/caseData/establishment/{establishmentId}`.
4. Correct a submitted case with `PATCH /oshaApi/v1/forms/caseData/{caseDataId}`, sending the `id` plus only the field(s) you're changing.
5. Never include employee names, SSNs, addresses, phone numbers, emails, or healthcare/family-member information in any case field, especially the narrative fields.
