ee49751c38 fix: add UTC timezone indicator to all datetime serialization 
Database stores times in UTC but serialized without timezone info,
causing frontend to misinterpret as local time. Now all datetime
fields include 'Z' suffix to indicate UTC, enabling proper timezone
conversion in the browser.

- Add UTCDatetimeBaseModel base class for Pydantic schemas
- Update model to_dict() methods to append 'Z' suffix
- Affects: tasks, users, sessions, audit logs, translations

87dc97d951 fix: improve Office document processing with Direct track 
- Force Office documents (PPTX, DOCX, XLSX) to use Direct track after
  LibreOffice conversion, since converted PDFs always have extractable text
- Fix PDF generator to not exclude text in image regions for Direct track,
  allowing text to render on top of background images (critical for PPT)
- Increase file_type column from VARCHAR(50) to VARCHAR(100) to support
  long MIME types like PPTX
- Remove reference to non-existent total_images metadata attribute

This significantly improves processing time for Office documents
(from ~170s OCR to ~10s Direct) while preserving text quality.

### 2. File Download System ✅
- Three format support: JSON / Markdown / PDF
- Endpoints: GET /api/v2/tasks/{id}/download/{format}
- File access control with ownership validation
- Frontend download buttons in TaskHistoryPage

### 3. Complete Task Management ✅
Backend Endpoints:
- POST /api/v2/tasks/{id}/start - Start task
- POST /api/v2/tasks/{id}/cancel - Cancel task
- POST /api/v2/tasks/{id}/retry - Retry failed task
- GET /api/v2/tasks - List with filters (status, filename, date range)
- GET /api/v2/tasks/stats - User statistics

Frontend Features:
- Status-based action buttons (Start/Cancel/Retry)
