feat(geoportal): one-click optimize-tiles + unified setup banner

New endpoint POST /api/geoportal/optimize-tiles:
- Slims gis_features view (drops attributes, enrichment, timestamps)
- Cascades to gis_terenuri, gis_cladiri, gis_administrativ, gis_documentatii
- Makes vector tiles dramatically smaller

Setup banner now checks 3 optimizations:
1. UAT zoom views (gis_uats_z0/z5/z8/z12)
2. Pre-computed geometry (geom_z0/z5/z8 columns)
3. Slim tile views (no JSON columns)

One "Aplica toate" button runs all pending steps sequentially.
