feat: add file report and transition filing status operations

[jfrench9]

Summary

Introduces two new ledger operations — File Report and Transition Filing Status — to the RoboSystems client SDK. This includes new API operation classes, request models, GraphQL query definitions, and ledger client integration.

Key Accomplishments

New API Operations

• op_file_report.py — Implements the file report operation against the RoboLedger extension API, enabling clients to programmatically file reports through the ledger system.
• op_transition_filing_status.py — Implements the transition filing status operation, allowing clients to move filings through their lifecycle states.

New Request Models

• FileReportRequest — Typed model encapsulating the parameters needed to file a report.
• TransitionFilingStatusRequest — Typed model encapsulating the parameters for transitioning a filing's status.

Client & Query Integration

• Extended LedgerClient with convenience methods for both new operations, maintaining a consistent API surface for consumers.
• Added corresponding GraphQL query definitions in the ledger query module to support the new operations.
• Updated models/__init__.py to export the new request models for public use.

Breaking Changes

None. This is a purely additive feature — no existing APIs, models, or behaviors are modified in a breaking way.

Testing Notes

• Verify that file_report and transition_filing_status methods on LedgerClient correctly construct and execute their respective operations.
• Validate request model serialization and field validation for both FileReportRequest and TransitionFilingStatusRequest.
• Test error handling for invalid inputs and unexpected API responses from both operations.
• Confirm the new GraphQL queries are well-formed and accepted by the target ledger API.

Infrastructure Considerations

• No new dependencies are introduced; the implementation follows established patterns in the existing codebase.
• The new operations rely on the existing RoboLedger extension API infrastructure — ensure the target environment supports the corresponding GraphQL endpoints.
• Consider adding these operations to any automated integration or contract test suites that cover the ledger client.
