72% of EKB quarters (1735/2408) have broken micro-precision geom in
cad_quarters_geom. NSPD returns valid quarter polygon in CAT_QUARTER_STATS
(36381) feature but Phase 4 was only consuming stats.
Add upsert_quarter_geom_from_feature: CTE-based UPDATE that transforms
3857 polygon to 4326 and writes only when existing geom is NULL or broken
(bbox width outside 100-10000m), verified via SQL-side sanity check.
Wire into Phase 4 with begin_nested savepoint: malformed NSPD GeoJSON
(self-intersecting ring) rollbacks only geom UPDATE, preserves
upsert_quarter_stats.
Closes part of #168 (follow-up data quality fix for #179).
Switch base search_by_quarter from thematicSearchId=1 to thematic=1
(includes ZOUIT in features). Add optional category_id param that routes
ZOUIT (36940/469039/469040/469042) -> thematicSearchId=5,
ENK (39663) -> thematicSearchId=15.
Add Phase 1.5 in harvest_quarter: for each PER_CATEGORY_PROBE_CATS
category present in meta_counts (meta_total>0), run dedicated
per-category search call. Skips if category in GRID_WALK_CATS and
bbox is valid (grid-walk gives better coverage).
Curl-probe confirmed NSPD API caps at 20/category with no pagination;
categoryId param is server-ignored; thematic=1 strictly better than
thematicSearchId=1 (includes ZOUIT).
Closes part of #168 (ZOUIT/ENK coverage gap).
