Add a CompanyName validated type enforcing 2-100 character length and
allowing only alphanumeric characters, spaces, hyphens, ampersands, and
periods. Applied to all endpoints accepting company names: /analyze,
/analyze/patent, /analyze/batch, /admin/tracked, and /export.
Includes unit tests covering too-short, too-long, special character,
leading-character, and valid edge cases for both single and batch
endpoints.
