perf(geoportal): zoom-dependent UAT simplification + Martin config + tile cache

PostGIS:
- gis_uats view: ST_SimplifyPreserveTopology(geom, 50) + only name/county/siruta
- gis_uats_simple view: ST_SimplifyPreserveTopology(geom, 500) for z0-z9

Martin config (martin.yaml):
- Explicit source definitions (auto_publish: false)
- gis_uats_simple (z0-9): only name+siruta, 500m simplified geometry
- gis_uats (z0-14): name+siruta+county, 50m simplified
- gis_terenuri (z10-18): object_id+siruta+cadastral_ref+area_value+layer_id
- gis_cladiri (z12-18): same properties
- 24h cache headers on all tiles

MapViewer:
- Dual UAT sources: simplified (z0-9) + detailed (z9+) with seamless handoff
- Zoom-interpolated paint: thin lines at z5, thicker at z12
- UAT labels only z9+, fill opacity z-interpolated (0.03→0.08)
