refactor: consolidate shared utilities and add script documentation

Browse Source 
- move common functions to utils.sh: init_paths, read_env_var, write_env_var,
  is_profile_active, load_env, gen_password, gen_hex, gen_base64, generate_bcrypt_hash
- add documentation headers to all installation scripts
- replace duplicate code with shared utility calls
- consolidate bcrypt hash generation loop in 03_generate_secrets.sh
- add DEBIAN_FRONTEND save/restore helpers for whiptail scripts
- standardize path initialization across all scripts

# 05_configure_services.sh - Service-specific configuration
# =============================================================================
# Collects additional configuration needed by selected services via whiptail
# prompts and writes settings to .env file.
#
# Prompts for:
# - OpenAI API Key (optional, used by Supabase AI and Crawl4AI)
# - n8n workflow import option (~300 ready-made workflows)
# - Number of n8n workers to run
# - Cloudflare Tunnel token (if cloudflare-tunnel profile is active)
#
# Also handles:
# - Generates n8n worker-runner pairs configuration
# - Resolves service conflicts (e.g., removes Dify if Supabase is selected)
#
# Usage: bash scripts/05_configure_services.sh
