Oleksandr Bezdieniezhnykh 142c6c4de8 Refactor constants management to use Pydantic BaseModel for configuration
- Replaced module-level path variables in constants.py with a structured Pydantic Config class.
- Updated all relevant modules (train.py, augmentation.py, exports.py, dataset-visualiser.py, manual_run.py) to access paths through the new config structure.
- Fixed bugs related to image processing and model saving.
- Enhanced test infrastructure to accommodate the new configuration approach.

This refactor improves code maintainability and clarity by centralizing configuration management.

# Phase 0: Context & Baseline
**Role**: Software engineer preparing for refactoring
**Goal**: Collect refactoring goals and capture baseline metrics
**Constraints**: Measurement only — no code changes
## 0a. Collect Goals
If PROBLEM_DIR files do not yet exist, help the user create them:
1. `problem.md` — what the system currently does, what changes are needed, pain points
2. `acceptance_criteria.md` — success criteria for the refactoring
3. `security_approach.md` — security requirements (if applicable)
Store in PROBLEM_DIR.
## 0b. Capture Baseline
1. Read problem description and acceptance criteria
2. Measure current system metrics using project-appropriate tools:
| Metric Category | What to Capture |
|----------------|-----------------|
| **Coverage** | Overall, unit, blackbox, critical paths |
| **Complexity** | Cyclomatic complexity (avg + top 5 functions), LOC, tech debt ratio |
| **Code Smells** | Total, critical, major |
| **Performance** | Response times (P50/P95/P99), CPU/memory, throughput |
| **Dependencies** | Total count, outdated, security vulnerabilities |
| **Build** | Build time, test execution time, deployment time |
3. Create functionality inventory: all features/endpoints with status and coverage
**Self-verification**:
- [ ] All metric categories measured (or noted as N/A with reason)
- [ ] Functionality inventory is complete
- [ ] Measurements are reproducible
**Save action**: Write `REFACTOR_DIR/baseline_metrics.md`
**BLOCKING**: Present baseline summary to user. Do NOT proceed until user confirms.
