c40b074 broke the image two ways:
- `cargo clean -p` removes 0 files, so the real sources (host mtimes
older than the step-1 stub build) were never recompiled and the image
shipped the 337KB fn-main stub, exiting 0 on start. Restore the
touch-based rebuild, which forces cargo to see every .rs as newer.
- bookworm-slim does not ship libssl3 despite the old comment; the bot
links OpenSSL via teloxide/reqwest native-tls, so restore the
libssl/libcrypto copies from the builder (same Debian release).

|

# dependency layer stays cached. (`cargo clean -p` does NOT work here — it
