IFAKA 9a3bb81337 fix: add NULL checks after malloc in drawBmp() (#80) ...

## Problem
`drawBmp()` allocates two row buffers via `malloc()` but doesn't check
if allocations succeed. On low memory, this causes a crash when the NULL
pointers are dereferenced.

## Fix
Add NULL check after both `malloc()` calls. If either fails, log error
and return early.

Changed `lib/GfxRenderer/GfxRenderer.cpp`.

## Test
- Defensive addition only - no logic changes
- Manual device testing appreciated
