perf(geoportal): materialize simplified UAT geometries (fixes 90% CPU on PostgreSQL)

ST_SimplifyPreserveTopology in views runs on every Martin tile request,
causing constant CPU load. Fix: pre-compute simplified geometries into
dedicated columns (geom_z0, geom_z5, geom_z8) on the GisUat table.

POST /api/geoportal/optimize-views:
1. Adds geom_z0/z5/z8 columns to GisUat
2. Backfills with pre-computed simplifications (one-time cost)
3. Creates GiST spatial indexes on each
4. Replaces views to use pre-computed columns (zero CPU reads)
5. Updates trigger to auto-compute on INSERT/UPDATE

Setup banner: now checks optimization status and shows "Optimizeaza"
button if needed. One-click, then docker restart martin.
