fix(docker): use curl-compatible flags in healthcheck commands

The Alpine→Debian migration changed wget to curl but kept wget-specific
flags (--no-verbose, --tries=1, --spider) which don't work with curl.

Changed to: curl -fsS (fail on error, silent, show errors)

Fixed in:
- docker-compose.yml
- docker-compose.e2e.yml
- docker-compose.local.yml

docker-compose.playwright.yml already had correct syntax.
