feat: Infor-style split-panel layout, projects page, fuzzy search, Odoo scaffold

Web UI - Infor CloudSuite-style split-panel layout (items.html rewrite):
- Replace modal-based item detail with inline split-panel workspace
- Horizontal mode: item list on left, tabbed detail panel on right
- Vertical mode: detail panel on top, item list below
- Detail tabs: Main, Properties, Revisions, BOM, Where Used
- Ctrl+F opens in-page filter overlay with fuzzy search
- Column config gear icon with per-layout-mode persistence
- Search scope toggle pills (All / Part Number / Description)
- Selected row highlight with accent border
- Responsive breakpoint forces vertical below 900px
- Create/Edit/Delete remain as modal dialogs

Web UI - Projects page:
- New projects.html template with full CRUD
- Project table: Code, Name, Description, Item count, Created, Actions
- Create/Edit/Delete modals
- Click project code navigates to items filtered by project
- 3-tab navigation in base.html: Items, Projects, Schemas

Fuzzy search:
- Add sahilm/fuzzy dependency for ranked text matching
- New internal/api/search.go with SearchableItems fuzzy.Source
- GET /api/items/search endpoint with field scope and type/project filters
- Frontend routes to fuzzy endpoint when search input is non-empty

Odoo ERP integration scaffold:
- Migration 008: integrations and sync_log tables
- internal/odoo/ package: types, client stubs, sync stubs
- internal/db/integrations.go: IntegrationRepository
- internal/config/config.go: OdooConfig struct
- 6 API endpoints for config CRUD, sync log, test, push, pull
- All sync operations return stub responses

Documentation:
- docs/REPOSITORY_STATUS.md: comprehensive repository state report
  with architecture overview, API surface, feature stubs, and
  potential issues analysis
