Fix incomplete Rack→Bin rename: missing file renames, stale UI labels, ReportManager property bug

- Rename rack_log.php → bin_log.php and rack_occupancy.php → bin_occupancy.php
  (occupy_rack.php was already calling bin_*.php, causing 404 on every load)
- Fix occupy_rack.php: page title, stat card label (add id="stat_label_bins"),
  section headings, and <th> column headers still read "Rack/Racks"
- Fix ReportManager: constructor wrote to $this->companyId (dynamic property)
  instead of the declared $this->company_id, causing all queries to filter on
  company_id = 0 under strict PHP 8.2+ property semantics
