feat: Flexoptix section — speed formatting + Lagerbestand display

Speed display: fix raw Gbps decimals → formatted labels
- 1600.00G → 1.6T (≥1000 Gbps converted to T)
- 400G → 400G (clean integer, no trailing .00)
- Helper function fmtSpeed() added in dashboard JS

Lagerbestand: add stock availability per transceiver
- getFlexoptixSuggestions() extended with LEFT JOIN LATERAL on
  stock_observations (latest row per transceiver)
- Returns warehouse_de_qty, warehouse_global_qty, backorder_qty,
  backorder_estimated_date
- Dashboard renders color-coded badges per row:
    green  = DE-Lager quantity
    blue   = Global-Lager quantity
    yellow = Zulauf with estimated delivery date if available
- Badges hidden when all quantities are null/zero (graceful fallback)
