[Part 2 / Phase 12] PathogenClassification: Cleanup and deprecation

[roldy]

Problem Description

Part of Epic: [Epic] PathogenClassification: Replace GenoTypeResult & SeroGroupSpecification enums
Blocked by: Phases 10 & 11

Remove the now-unused GenoTypeResult and SeroGroupSpecification enums and any remaining
usages in exports, reports, or other mapping code.

Proposed Solution

Tasks

• Delete sormas-api/.../sample/GenoTypeResult.java
• Delete sormas-api/.../sample/SeroGroupSpecification.java
• Search all export/report code for usages of genoTypeResult / seroGroupSpecification field names — update to pathogenClassification
• Search ExternalMessageMapper and any import/export mappers for seroTypingMethod / serotypingmethod — verify still intact (should be unaffected)
• Search for any remaining usages of the deleted enums across the codebase — compile will catch most
• mvn compile full project — zero errors
• Run affected tests

Additional Information

Verification

• API responses: old genoTypeResult / seroGroupSpecification fields absent; pathogenClassification present
• Exports/reports updated to use new field captions
• Backward compatibility check for any API consumers documented

Acceptance Criteria

• Full project compiles cleanly
• No references to GenoTypeResult or SeroGroupSpecification remain in production code
• All affected tests pass
