Refactor PDF generation workflow, integrate YAML-based event config, and simplify Makefile scripts.

- Replace `generate-personalized` with unified `generate` target in Makefile, supporting event config integration.
- Add YAML parsing to `generate_cards.py` for event-level placeholders and back side generation.
- Update templates to include `EVENT_*` placeholders and dynamic content rendering.
- Simplify `build` and `build-personalized` targets; consolidate redundant logic.
- Enhance `make help` documentation for updated workflow.
- Adjust LaTeX formatting for back side templates, removing hardcoded spacing.
