Split audits into Weigh Ins (bulk) and Bin Checks (discrete)

Replaces the unified audit system with two purpose-built flows:
- Weigh Ins: rebranded audit flow for bulk products (Flower, Concentrate,
  Tincture) with scale weigh, container weigh, and estimate modes
- Bin Checks: new bin-level presence check — select a bin, scan every item,
  resolve discrepancies (wrong bin, unknown, missing), auto-records presence
  audits on verified items

Adds cadence_days and last_checked to bins table, with per-bin overdue
tracking on the dashboard and bins view.
