根因：models.json 的 filePath 是相對路徑（"data/nef/kl520/xxx.nef"），
但 server working directory 是 {app}\bin\（app.go 設 cmd.Dir = binary 目錄），
所以 server 在 {app}\bin\data\nef\ 找 .nef 檔，找不到。

實際位置：{app}\data\nef\（installer 裝的位置），對應 server 的 --data-dir
由 Wails app 傳入的 %APPDATA%\visiona-local（或 fallback 到 <exe>/../data）。

修法：
- flash.NewService 新增 dataDir 參數
- StartFlash 中把相對 filePath 用 dataDir 拼接成絕對路徑：
  "data/nef/..." → 去掉 "data/" 前綴 → dataDir + "/nef/..."
- main.go 傳 dataDir 給 flash.NewService
