fix: Gitea Traefik routing and connection pool optimization

- Remove middleware reference from Gitea Traefik labels (caused routing issues)
- Optimize Gitea connection pool settings (MAX_IDLE_CONNS=30, authentication_timeout=180s)
- Add explicit service reference in Traefik labels
- Fix intermittent 504 timeouts by improving PostgreSQL connection handling

Fixes Gitea unreachability via git.michaelschiemer.de

+# Complete Deployment Playbook
+# Combines all deployment steps into a single Ansible run:
+# 1. Deploy Application Code
+# 2. Deploy Docker Image
+# 3. Install Composer Dependencies
+#
+# This reduces SSH connections and Ansible overhead compared to running
+# three separate playbook calls.
+#
+# Usage:
+#   ansible-playbook -i inventory/production.yml playbooks/deploy-complete.yml \
+#     -e "deployment_environment=staging" \
+#     -e "deployment_hosts=production" \
+#     -e "image_tag=latest" \
+#     -e "docker_registry=registry.michaelschiemer.de" \
+#     -e "docker_registry_username=admin" \
+#     -e "docker_registry_password=password" \
+#     -e "git_branch=staging" \
+#     --vault-password-file /tmp/vault_pass
+
+# Step 1: Deploy Application Code
+- import_playbook: deploy-application-code.yml
+
+# Step 2: Deploy Docker Image
+- import_playbook: deploy-image.yml
