fix: Center map directly on selected station by removing longitude offset.

feat: Implement caching for enriched station data loading and update map tooltip variable.

feat: Migrate interactive map from Leaflet to MapLibre, introducing dynamic basemap switching and updated map controls.

feat: Implement granular DWD parameter metadata extraction and caching, add `soil_temp_min_5cm` parameter, fix "ghost pressure" data, and enhance map highlighting flexibility.

perf: Optimize DWD data parsing by switching to `data.table::fread` with string-based date pre-filtering and consolidate library imports.

refactor: Consolidate map station highlighting into a new helper function, update helper sourcing, and fix map rendering on tab switch.
