feat(phase-13): update frontend types and API clients for Red/Blue workflow (T-113, T-114)

T-113: Rewrite models.ts with v2 types - TestState now includes red_executing/blue_evaluating, add TeamSide, ValidationStatus, TestTemplate, TestTemplateSummary, TestTimelineEntry types, RED_EDITABLE_STATES/BLUE_EDITABLE_STATES constants, and dual validation fields on Test interface. Remove old validated_by/validated_at references from TestDetailPage and techniques API.

T-114: Rewrite tests.ts API client with 16 functions covering full Red/Blue workflow (createTestFromTemplate, updateTestRed/Blue, startExecution, submitRed/Blue, validateAsRedLead/BlueLead, reopenTest, getTestTimeline). Rewrite evidence.ts with team parameter on upload/list and new deleteEvidence. Create test-templates.ts with getTemplates, getTemplateById, getTemplatesByTechnique, createTemplate, importAtomicTests.
