feat: add automatic firmware build on version tags

Improvements to build-secubox-images.yml workflow:
- Added automatic trigger on version tags (v*.*.*)
- Auto-build all devices when triggered by tag push
- SecuBox packages included by default on tag builds
- Fixed release creation logic (use tag name, not run number)
- Mark pre-releases automatically (alpha/beta/rc tags)
- Better handling of workflow inputs with fallback defaults
- Enhanced build summaries with tag information

Now you can trigger firmware builds by pushing tags like:
  git tag v0.1.3-alpha && git push origin v0.1.3-alpha
