feat: implement filter presets and view state persistence across dashboard, run details, product list, and stalker explorer

- Added functionality to save, update, and apply filter presets for various views.
- Introduced local storage management for persisting view states across sessions.
- Enhanced dashboard, run details, product list, and stalker explorer components to utilize saved filter presets.
- Updated UI to include controls for managing filter presets.

 - Supplier UPC files resolve UPC/EAN through SP-API catalog lookup first; Keepa UPC lookup is fallback only (no-match or request-failure cases).
 - Supplier workbook output must keep `Ranked Leads`, `Skipped`, and `Summary` sheets.

+- Store time-varying data in observations or revisions and retain run history rather than overwriting prior analysis.

+## Persistent Storage
 
-Results from each run are now stored in a SQLite database named `db/results.db` by default. The SQLite implementation details are handled in `src/database.ts`. This allows you to:
+PostgreSQL persistence is managed with Drizzle in `src/db/schema.ts` and `src/db/persistence.ts`. ASINs are canonical product identities: all inputs normalize to uppercase 10-character alphanumeric keys before any product reference is stored.
 
-- Revisit past analysis results.
-- Query and analyze historical data.
-- Track product performance over time.
+Core tables:
 
-The database will automatically be created if it doesn't exist. Two tables are created:
+- `products`: one canonical row per ASIN with latest descriptive metadata.
+- `product_observations`: append-only marketplace, pricing, fee, and sellability snapshots.
+- `runs` and `run_items`: unified lifecycle/history for lead, category, supplier UPC, and stalker workflows.
+- `analysis_revisions` and `supplier_scores`: append-only analysis results; reanalysis does not overwrite prior decisions.
+- `sourcing_inputs`, `upc_resolutions`, and `product_identifiers`: source-row and confirmed identifier data kept separate from catalog products.
+- `stalker_run_details`, `stalker_scans`, and `stalker_inventory_items`: seller workflow provenance linked back to products and observations.
 
-- `runs`: Stores metadata about each analysis run (timestamp, input file, output file, and summary counts).
-- `results`: Stores detailed analysis results for each product from each run, linked to the `runs` table.
+Unresolved or ambiguous supplier UPCs stay on their run item and resolution records; a UPC is never stored as an ASIN.
+
+Web endpoints use unified identifiers:
+
+- `GET /api/runs`, `GET /api/runs/:runId`, `GET /api/runs/:runId/items`
+- `GET /api/products`, `GET /api/products/:asin`
+- `POST /api/run-items/:itemId/reanalyze`
