fix(olv): correct stamp pixel format and work buffer size

Three fixes from Cafe SDK manual:

1. Transparent pixels must be (255,255,255,0) not (0,0,0,0).
   AddStampData validates every pixel is one of: black (0,0,0,255),
   white (255,255,255,255), or transparent (255,255,255,0). Our previous
   transparent value (0,0,0,0) is not in this set → ResultInvalidFormat.

2. Work buffer increased to 1 MB (POST_APP_PARAM_WORK_BUFF_SIZE).
   Previous 512 KB was below the required minimum.

3. Image descriptor kept at 0x08 (8 alpha bits, bottom-left) — confirmed
   correct from SDK example TGA header: 00 00 02 ... 20 08.
