feat(database): update TimescaleDB Docker images to pg18

- Changed Docker images in various configurations and test utilities from `timescale/timescaledb:latest-pg17` to `timescale/timescaledb-ha:pg18` for improved performance and compatibility.
- Updated the contributing guide, docker-compose file, and multiple test files to reflect the new image version.
- Removed outdated documentation files related to GitHub installation flow and backup/restore test utilities to streamline the repository.

This commit enhances the database setup by ensuring the use of the latest TimescaleDB version, improving overall stability and performance.
