Org inventory management UI

[GitAddRemote]

User Story

As an organization member, I need a dedicated org inventory page that shows org-owned items and member-contributed items with clear ownership labeling, filtered by category and ownership type, and respects my role permissions (read-only vs. editable), so that I can manage and review my organization's collective inventory without confusion about who owns what.

Background

Updated to reflect finalized schema. Inventory is now backed by station_inventory_item with polymorphic owner_type/owner_id ownership. Org-owned rows have owner_type = 'org'. Member-contributed rows have owner_type = 'user' and is_org_available = TRUE. See docs/schema/inventory-catalog-design.md.

Definition of Done

• Dedicated /org-inventory route and page component created
• Page displays two labeled sections: Org-Owned and Member-Contributed
• Ownership-type filter: All | Org-Owned | Member-Contributed — updates without page reload
• Category filter: populated from GET /api/catalog/categories, multi-select
• Pagination: server-side, 50 rows per page
• Permission-aware rendering: users without canManageInventory see read-only rows
• Org inventory summary section (aggregate totals) above the item list
• pnpm typecheck passes

Acceptance Criteria

• GET /api/inventory?ownerType=org&ownerOrgId=:id returns org-owned rows (owner_type='org', owner_id=:id)
• GET /api/inventory?ownerType=user&orgId=:id&orgAvailable=true returns member-contributed rows (is_org_available=TRUE for members of the org)
• A user in Org A cannot retrieve inventory for Org B by substituting orgId
• Summary totals match sum of quantities for the same filters

Depends on

• feat: station_inventory_item migration replacing user_inventory_item #279 — station_inventory_item migration
• Catalog API: unified GET /api/catalog endpoint for items, vehicles, and commodities #200 — GET /api/catalog endpoint
• Frontend: update inventory picker to use unified /api/catalog endpoint #203 — catalog picker component
• Frontend: commodity-specific quantity fields with SCU and μSCU unit selector #204 — unit selector
• Frontend: normalized location picker backed by station_* location hierarchy #205 — location picker
