filebrowser.sh: full Caddy config in standalone stub (not just info msg)

Replace the "configure manually" stub with a real implementation that
matches common.sh's configure_caddy_for_service behaviour:
- Prompts to configure (skippable)
- Asks for domain with example hint
- Backs up Caddyfile before writing
- Checks for duplicate domain entry, offers overwrite
- Appends site block with reverse_proxy, security headers, JSON log
- fmt + reload via docker exec caddy caddy fmt/reload

Used when filebrowser.sh is run standalone without the repo present.
When the repo is present (common.sh sourced), the real function is used.
