fix(types): eliminate all explicit any types across codebase

Replaced 57 `any` usages with proper types:
- Test mocks: Partial<ServiceType> instead of any
- Test assertions: AuthenticatedRequest interface for extended props
- Delete operations: Record<string, unknown> for object manipulation
- Logger: LogEntry interface, eslint-disable for interface requirements
- Controller: GpuHistoryItem interface for GPU history data

All 333 tests passing. ESLint now at 0 errors, 0 warnings.
