Conversation
- Integrated `StandaloneBoundaryImporter` service to enable standalone administrative boundary imports. - Added H3 (Uber H3) dependency for high-resolution geospatial indexing. - Updated import logic to process boundaries from PBF files and store outputs in RocksDB databases. - Enhanced geometry processing with support for buffering, simplification, and H3 polygon-to-cell mapping.

- Added `SimplificationConfiguration` to `PaikkaConfiguration` to support configurable tolerances for geometry simplification. - Replaced hardcoded tolerance values in `GeometrySimplificationService` with values from configuration. - Updated tests to inject `PaikkaConfiguration` into `GeometrySimplificationService`. - Adjusted test properties and application configuration files to define default tolerance values.
… logging - Introduced SLF4J logger to `StandaloneBoundaryImporter` for comprehensive logging. - Added detailed geometry validation with repair logic for invalid geometries. - Replaced `polygonToCellsH3` with optimized `processCellsH3Stream` for better scalability. - Improved handling of simplified geometries and batch processing for H3 cells. - Made simplification tolerances configurable in `application-dev.properties`.

- Added unit tests for boundary lookup with additional locations (e.g., Pölzig). - Adjusted RocksDB options to remove read-only constraint for enhanced flexibility. - Updated assertions to verify total cell counts and boundary hierarchy integrity.

…nd upload - Introduced `scripts/update-h3.sh` to automate H3 bundle generation. - Supports configurable options for memory, threads, and input paths. - Includes filtering, data import, bundling, and optional upload to R2 storage. - Enhanced error handling and directory preparation for seamless execution.
- Added `prepare-boundaries` command with symlink and execution setup in Dockerfile. - Updated `update-h3.sh` to rename filtered PBF output and disable Docker image pull. - Fixed `filter_boundaries.sh` to correct typo in description. - Simplified `import-boundaries.sh` by removing unnecessary cleanup steps.
