fix: Resolve critical Codacy security and best practice issues

Security Fixes (HIGH):
  - Enable force_ssl in production with ENV override support
   - SSL enforcement now defaults to true, can be disabled via FORCE_SSL=false

   Best Practice Fixes (MEDIUM):
   - Add --no-install-recommends to Dockerfile apt-get
   - Add proper quoting to shell scripts to prevent globbing/word splitting
   - Replace rescue modifier with explicit begin/rescue block

   Code Style Fixes:
   - Fix trailing whitespace in production.rb
   - Convert double quotes to single quotes where appropriate
   - Fix lambda syntax (use lambda instead of ->)
   - Mark unused lambda parameters with underscore prefix
   - Fix indentation issues

   Files modified:
   - config/environments/production.rb (security + style)
   - Dockerfile (best practice)
   - backup.sh, deploy/scripts/backup.sh (shell quoting)
   - security_tests/start-security-lab.sh (shell quoting)
   - config/initializers/row_level_security.rb (rescue modifier)
