Subject: [PATCH] fix(stock): repair Flexoptix stock write path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two bugs blocked all Flexoptix stock_observations:
1. db.ts: compatible_brands null param needs ::text[] cast; price_currency needs
   ::bpchar cast in stock_observations INSERT
2. flexoptix-api-sync.ts: UPDATE transceivers used $1 in WHERE IS NOT NULL clause
   without explicit type cast — PostgreSQL cant infer type of untyped null params
   in WHERE context. Fixed with $1::text / $2::text casts.

Result: 346 stock observations written on first run after fix.
