darktable-inspired reskin + metadata/collections, map, easy mode, select/export

UI overhaul to a darktable tone-and-manner and a set of features adapted from
darktable's proven patterns (reimplemented in our Electron/TS stack; no GPL code).

Design reskin:
- Dark neutral-gray palette + amber accent, flat/squared corners, no card shadows,
  compact darktable-style top bar (logo + pipe-separated view tabs), denser 15px base
- Done via design tokens (Tailwind slate/brand/radius/shadow remap) — minimal churn

Metadata & collections (Phase A/B):
- exifr now captures GPS + camera; asset table ALTER-migrated (gpsLat/gpsLon/camera,
  metaVersion backfill on re-index)
- Collection facet bar (year timeline / camera / color-label) filters the grid

Map & relation finder (Phase C):
- Leaflet + online OSM map tab; geotagged photos as markers
- relationService: related photos by place (GPS<1km) + time (+/-2d) + CLIP similarity

Easy mode (Phase D):
- easyMode setting (menu / onboarding); scales the whole UI (rem) + bigger thumbnails
  + large icon nav with plain labels (4050 accessibility)

Library usability:
- Video thumbnails (representative frame capture in the inference worker)
- Media filter (All / Photos / Videos) to separate them
- Clearer culling labels ("Good shots" / "To cull") + explanation tooltip
- Multi-select tiles -> Export selected to a folder (copy, best-cut extraction) and
  Delete to Recycle Bin (shell.trashItem) behind a confirm dialog
- ONNX Runtime wasm bundled locally (offline) via copy-ort-wasm + asarUnpack

Docs: DARKTABLE_REVIEW (feasibility + roadmap A->D). All typecheck/tests/build green;
boot smoke verified each phase.
