feat(docker-runtime): unified Debian-based images, dynamic path resolution & enhanced UNO/LibreOffice handling (#4880)
# Description of Changes

### What was changed

This PR introduces a major refinement to the Docker runtime, system path
resolution, conversion tooling, and integration logic across the
codebase. Key improvements include:

- Migration of **Dockerfile**, **Dockerfile.fat** to a unified
Debian-based environment.
- Introduction of **RuntimePathConfig** enhancements to dynamically
resolve:
  - `weasyprint`, `unoconvert`, `calibre`, `ocrmypdf`, `soffice`
  - Tesseract `tessdata` paths with Docker-aware defaults.
- Support for **UNO server (unoserver/unoconvert)** as primary document
converter with automatic fallback to `soffice`.
- Isolation of Python environments for WeasyPrint and UNO tooling.
- Updated controllers and services to correctly inject
`RuntimePathConfig`.
- Improved process execution logic in converters and OCR handling.
- Major updates to `init.sh` and `init-without-ocr.sh`:
  - Unified environment initialization
  - Proper UID/GID remapping
  - Safer permissions handling
  - Automatic Tesseract path detection
  - Reliable startup of headless LibreOffice + Xvfb + UNO server
- Full test suite updates:
  - Adaptation to new conversion paths
  - Mocking of UNO and LibreOffice commands
  - More robust Docker test logic
- Updated example docker-compose files referencing GHCR test images.
- Expanded configuration schema for new operations paths.

### Why the change was made

These changes address long-standing issues around:

- Inconsistent or missing binary paths between image variants.
- Reduced reliability of document conversions (UNO vs. soffice).
- Lack of uniform runtime initialization across Docker images.
- Repetitive environment setup logic split across multiple scripts.
- Fragile test scenarios tied to Alpine-based images.

Switching to a unified Debian-based runtime significantly improves:

- Compatibility with LibreOffice, Calibre, WebEngine and graphics stack.
- UNO stability for document conversions.
- Tesseract deterministic behavior.
- Debuggability and reliability of CI/CD Docker-based tests.

The improvements to `RuntimePathConfig` ensure all system binaries are
fully configurable and correctly detected at runtime.
