Bugfix Issue 714 Expand Dockerignore

Bugfix Issue #714: Expand .dockerignore (critically incomplete)

Summary

The .dockerignore only excluded 4 entries, causing ~184MB of unnecessary files to be sent to Docker context on every build.

Root Cause

.dockerignore:1-4 only excluded .env, .env.example, docker-compose.yml, Dockerfile. Dockerfile:20 uses COPY . . which copies everything not excluded.

Impact

• .git/ (114M) — git history
• vendor/ (28M) — PHP dependencies (reinstallable)
• tmp/ (29M) — temporary files
• docs/ (11M) — documentation
• composer.phar (2.2M) — PHP archive

Total: ~184MB sent to Docker context unnecessarily.

Fix

Expanded .dockerignore to 17 entries:

.env
.env.example
docker-compose.yml
Dockerfile
vendor/
node_modules/
tl200/
.git/
.gitignore
logs/
upload_area/
*.phar
tmp/
composer.phar
php.ini
.squash.yml
docs/

Verification

• All necessary application files (api/, gui/, config.inc.php) remain included
• Excluded paths verified present in repository
• docker build should complete successfully with smaller context
