chore(mods): classify 11 new distribution mods

Distribution added 11 jars. classify-mods.py seeds all as `both`
(none declare CLIENT in neoforge.mods.toml). Hand-flip the two
pure-client cosmetic ones so sync-server-mods.sh drops them:

- ExtremeSoundMuffler: client-side sound muffling UI
- ToastControl: client-side toast popup suppression

Rest stay `both` — Placebo/moonlight/caelus are libs, and
amendments/etched/fishingoverhaul/immersive_paintings/
createornithopterglider/emotecraft add server-side content or sync.

Also map iris as `client`. It is referenced by distribution.json but
absent from the local (gitignored) dist jar dir, so classify-mods.py
never sees it; mapping it keeps mods-sides.json aligned with the
manifest. Client-only, so the sync selection is unchanged.

server-mods/ now 130 jars (was 123).

+## Simple Voice Chat — `voice_host` (NOT repo-tracked)
+
+Voice chat is UDP `24454/udp`, published in compose. The mod auto-generates
+`/data/config/voicechat/voicechat-server.properties` in the `mc_data` volume.
+
+**Gotcha — `voice_host` must be set or remote clients get a red/crossed icon.**
+Behind any NAT/Docker the server announces an address for clients' UDP
+connection; if `voice_host=` is empty it auto-detects the internal Docker IP →
+unreachable → the secret (TCP) is sent but the UDP handshake never completes
+("Sent secret" with no following "successfully connected to voice chat").
+
+Set on prod:
+
+```
+docker exec minecraft sed -i 's/^voice_host=.*/voice_host=ulicraft.net/' \
+  /data/config/voicechat/voicechat-server.properties
+docker restart minecraft   # mod reads props only at startup
+```
+
+**⚠️ This value lives in the `mc_data` volume, NOT auto-managed from this repo.**
+It survives restarts and `compose down/up`, but a **world wipe / fresh `mc_data`**
+regenerates the file with `voice_host=` empty → voice silently breaks again.
+
+A known-good prod snapshot is committed at
+`server-configs/voicechat-server.properties` (reference copy, `voice_host=ulicraft.net`).
+After a world reset, either re-run the `sed` + `docker restart` above, or restore
+the snapshot:
+
+```
+docker cp server-configs/voicechat-server.properties \
+  minecraft:/data/config/voicechat/voicechat-server.properties
+docker restart minecraft
+```
+
+(Snapshot is not auto-mounted — to make it durable, add a bind mount of
+`server-configs/voicechat-server.properties` into `/data/config/voicechat/` in
+compose.)
+
+Verify after a client joins:
+`docker logs minecraft 2>&1 | grep -i "connected to voice"` → expect
+`Player <name> ... successfully connected to voice chat`.
+
+Note: a red voice icon can ALSO be client-side — a VPN/zero-trust client
+(Cloudflare One/WARP, FortiClient) on the player's machine silently drops the
+voice UDP. Rule out VPNs before touching the server.
