chore: move generated images and database outside the git worktree

The output/ and data/ directories lived inside this git repo. They are
gitignored, so any rebuild of the directory (git clone into a recreated
path, rm + clone) silently took the generated images and the SQLite
database with it. On 2026-11-04 that cost a full round of regenerated
images.

The real data now lives in /root/apps/ai-image-data/:
  output/  generated images, one subdirectory per profile_name
  data/    ai_image.db + secret.key

Bind mounts use absolute paths so the container never depends on symlink
resolution. ./output and ./data remain as symlinks for backwards
compatibility with existing scripts and skills.

Also ignore the symlinks themselves: the directory-form rules do not
match them, so git would have picked them up.
