Add UI and styling documentation; remove idempotency and logging audits

- Introduced a new document outlining UI structure, reusable template components, CSS variable conventions, and per-page data/actions for the CalMiner application.
- Removed outdated idempotency audit and logging audit documents as they are no longer relevant.
- Updated quickstart guide to streamline developer setup instructions and link to relevant documentation.
- Created a roadmap document detailing scenario enhancements and data management strategies.
- Deleted the seed data plan document to consolidate information into the setup process.
- Refactored setup_database.py for improved logging and error handling during database setup and migration processes.
