Juan DenisandClaude Fable 5 e797ec3a3f fix(system): version resolution honors custom install dirs and Docker
The About page's /system/version (and check-update's current-version
read) hardcoded /opt/serverkit first, duplicated in three places:

- app/utils/version.py is now the single resolver: explicit
  SERVERKIT_INSTALL_DIR override -> the running code's own tree ->
  /opt/serverkit last (a box moved to a custom dir may still have a
  stale tree there); system.py's two inline copies now call it
- the systemd unit template renders SERVERKIT_INSTALL_DIR from the
  installer's SERVERKIT_DIR (deliberately not the bare SERVERKIT_DIR
  env name, which app/paths.py already uses for the /var/serverkit
  data root); flows to existing installs via the updater's re-render
- crypto's .env discovery gains the same install-dir hint
- Docker image now ships VERSION (/app/VERSION) — containers showed
  the 1.0.0 fallback because no candidate path existed in the image
- 4 proving tests in backend/tests/test_panel_version.py

# ============================================
# ServerKit Dockerfile - Single Container
# ============================================
# This Dockerfile creates a single container with both
# frontend and backend. Good for simple deployments.
#
# For production with separate containers and nginx,
# use docker-compose.yml instead.
#
# Build: docker build -t serverkit .
# Run: docker run -d -p 5000:5000 --env-file .env serverkit
# Override the internal backend port with SERVERKIT_BACKEND_PORT if needed.
# ============================================
