Make Docker installs resilient: install first, config later

Changes the installation pattern for Docker apps to be more robust:
- Install docker-compose.yml FIRST (always succeeds)
- THEN try configuration with prompts
- Use sensible defaults if prompts fail
- Continue to next app even if current config fails
- Added || true and 2>/dev/null to prevent script stops

Updated apps: Frigate, Frigate-Notify, Caddy, ddclient

Config templates now include clear warnings:
- "YOU MUST EDIT THIS FILE" for required configs
- "YOU MAY NEED TO EDIT THIS FILE" for optional configs
- Links to documentation

This ensures the script completes even with complex interdependent
services that may need manual configuration after install.
