fix(build): resolve three failing tests across integration and tui modules

SessionOrchestratorIntegrationTest: wire approvalRepository into
OrchestratorRepositories constructor which gained the field in the kernel
refactor. TambouiKeyMapperTest: correct ctrl-h to alt-h — the mapper has
always placed ToggleApprovalOverlay under the Alt branch, not Ctrl.
SessionOrchestrator.emit: replace substring(0,7) with take(7) to avoid
StringIndexOutOfBoundsException when session IDs are shorter than 7 chars.
