🐛 Fix printf %q empty-var bug; sync Dockerfile; update README 🐛

Three fixes in this commit:
1. printf '%q' empty-variable bug — all 7 init.d service scripts:
printf '%q ' $su_exec/\$args/\$extra_env with an unset/empty variable
calls printf with no vararg, causing bash to format the empty string
as '' (two single-quotes), which gets written into the generated exec
script and makes the container fail to start. Fixed with ${var:+...}
parameter expansion so an empty variable produces an empty string.
2. Dockerfile — sync to template 202605261603 (structural changes:
blank line after $SHELL_OPTS in apk-repos block, un-indented echo ""
in Custom Settings and Custom Applications stubs); preserve all
tor-specific values (IMAGE_NAME, PHP_SERVER, BUILD_DATE, SERVICE_PORT,
EXPOSE_PORTS, PHP_VERSION, IMAGE_REPO, CONTAINER_VERSION, PULL_URL,
PACK_LIST, HOSTNAME, OCI labels).
3. README.md — add the full EXPOSE_PORTS list to the docker run command
and docker-compose ports section (privoxy 8118, SOCKS5 9050, DNS 9053
TCP+UDP, web 9080, bridge range 57000-57007).
