Description

1. Various dependency updates.
2. Adds three new API clients for USPTO Office Action data endpoints:

• OAActionsClient — Office Action Text Retrieval API (v1): full-text office action documents including body text and structured section data (§101/102/103/112 rejections, citations, etc.)
• OARejectionsClient — Office Action Rejections API (v2): rejection-level records with rejection type indicators (hasRej101/102/103/112/DP), claim arrays, and examiner classification metadata
• OACitationsClient — Office Action Citations API: enriched citation records from office actions including cited document identifiers, legal section codes, and examiner-cited indicators

All three clients provide convenience query parameters for common fields.

Additional Notes

Each client follows the established patterns from EnrichedCitationsClient. The base.py form-urlencoded branch in _get_model was extended to include all three new response types. Config and environment variable
support added for all three base URLs (USPTO_OA_ACTIONS_BASE_URL, USPTO_OA_REJECTIONS_BASE_URL, USPTO_OA_CITATIONS_BASE_URL).
