Review view: cause-grouped UI with actions + suggestions

Builds a dedicated /review route that mirrors /duplicates' chrome:
- /review/+page.svelte mounts Toolbar + ReviewView + RightSidebar
- CauseGroupCard.svelte renders one card per cause with Approve all
  and Archive all bulk actions plus a per-cause suggestion line
- CauseBadges.svelte shows every matching cause as chips on each tile
- services/adapters/review.ts fetches review:true and groups photos
  by primary cause; current taxonomy is low_resolution >
  stripped_exif > implausible_year > non_image_type > quality_other
  (low_resolution ranks first because it's the most actionable signal)

Sidebar gains an opt-in showRelated prop that adds three
RelatedStrip panels (same folder / camera / year) for the
'decide these together' workflow.

LeftSidebar's Review entry switches from a section filter to a
route link so /review picks up the click.

PpPhoto gains the missing Resolution field PhotoPrism actually
returns on list responses.
