Merge pull request 'Allowed IPs take the full settings reload after a write' (#42) from fix/allowed-ip-reload into main

write_reload_target sent AllowedIp writes to the blocked-IP reload, but
that reload rebuilds only BlockedIps. Allowed IPs are parsed into the
core's security settings (Security::parse), which only a full reload
rebuilds, so an AllowedIp write reported x:settingsReload applied: true
while the change wasn't live until the next full reload.

AllowedIp now maps to the full reload, like the other settings objects;
BlockedIp keeps its targeted reload.

system::auto_reload::settings_reload_tests now creates an allowed IP
over JMAP and checks that is_ip_allowed sees it with no ReloadSettings,
and that destroying it takes it out again. On main it fails ("allowed
IP not in the running settings").

+//! inbuxa: the spam filter rules that ship with the server.
+//!
+//! Upstream fetches its latest published rules from GitHub at run time, so
+//! scoring changes with a release nobody here tested and depends on reaching
+//! it. The fork embeds a pinned copy (resources/spam-filter/, with its version
+//! and license) and uses it whenever no other source is configured. The rules
+//! URL remains an operator override (`https://` or `file://`).
+//!
+//! Loading rules only ever adds what's missing, never changes an existing rule
+//! or score. They load on first boot, and again whenever the bundled version
+//! differs from the one last applied, so an upgrade brings new tags (the AI
+//! classifier's `LLM_*` scores, say) to an install that already had rules.

+unmodified. The server embeds it (`crates/common/src/manager/spam_rules.rs`)
+and loads it whenever no other rules source is configured, so a release
+scores mail with the rules it was tested with, offline and with nothing to
+fetch. The rules URL setting stays an operator override.
+
+The rules are dual-licensed MIT or Apache-2.0, Copyright (C) 2024, Stalwart
+Labs LLC; the fork takes them under MIT, with the notice in `THIRD-PARTY.md`.
+
+They include the scores for the AI classifier's tags (`LLM_*`, 3.0 for the
+high-confidence spam categories, −3.0 for legitimate), which match
+`docs/spec/features/ai-spam-classification.md`.
+
+## Updating
+
+The `upstream-watch` workflow opens an issue when spam-filter publishes a
+newer release. To take it:
+
+1. Download `spam-filter-rules.json.gz` from that release, pinned by tag
+   (`releases/download/vX.Y.Z/…`, not `latest`), over this file.
+2. Set `BUNDLED_SPAM_RULES_VERSION` in `spam_rules.rs` and the version in
+   this README and in `THIRD-PARTY.md`.
+3. Run the antispam test (`STORE=RocksDb RUST_MIN_STACK=16777216 cargo test
+   -p tests --lib -- smtp::inbound::antispam::antispam --exact`) and fix
+   expectations the new rules change, knowingly.
+
+On the next start each server loads the new version once. Loading only adds
+rules and tags that are missing; it never changes an existing one, so an
+operator's own adjustments survive.
