fix(tui): prevent image ID collisions between modules

- allocateImageId() now returns random IDs instead of sequential
- Static images no longer auto-allocate IDs (transient display)
- Only explicit imageId usage (like DOSBox) gets tracked IDs
- Suppress emulators exit logging in DOSBox dispose

Fixes image replacement bug when extension and main app both
allocated sequential IDs starting at 1.
