Merge pull request 'Release 2026.9.28.4' (#94) from release/2026.9.28.4-pr into main

The personal-data catalog and what it feeds: the data inventory and its
snapshots (#83, #89), the Compliance Officer roles (#88), the Compliance
Overview and Data Inventory menu entries (#92). Log file retention
(#87), privacy defaults for new installs (#85, #90), webhooks that send
only the events they name (#82), and upstream v0.16.24 (#84), whose
spam rules updates keep what an admin edited.

Explain: 12 settings asked about (upstream's new createdAt fields, the
certificate dates and the webhook events policy), with the release's
recommended model built locally; 705 answers carry over.

+## Added
+- DNS: PowerDNS Authoritative provider for automatic DNS record management.
+
+## Changed
+
+## Fixed
+- Troubleshoot tool: `TLSA` records are looked up for every MX host, including hosts whose zone is not DNSSEC signed.
+- Spam filter:
+  - OpenPhish and PhishTank entries containing uppercase characters never match, since message URLs are lowercased while HTTP lookup entries keep their original case. HTTP lookups now match keys case-insensitively.
+  - URL shortener links are followed using the lowercased URL, so case-sensitive short links resolve to the wrong destination or not at all.
+  - Incremental training never advances its position past the first run, so every retained sample added since then is trained again, and counted again in the reservoir, on each run until it expires.
+  - Updating the rules only adds new objects, so upstream changes to existing rules, DNSBL servers, HTTP lookups, lookup keys and file extensions never reach an existing installation.
+  - Updating the rules reports success when objects fail to import, or when a configuration error stops the updated settings from being activated.
+- JMAP:
+  - A `PushSubscription` created within the verification rate limit window of another one on the same account never receives its `PushVerification`, since the blocked verification is dropped instead of being sent once the window expires.
+  - A push notification retried after a failed delivery can report an older state than a change queued during the failed attempt, since the older state changes are merged last and overwrite the newer ones.
+  - Changes made while a push request is in flight are not delivered until the next change reaches the same subscription, since a successful delivery cancels the pending retry.
+  - The VAPID `aud` claim is derived from a hand-written parse of the push URL, so a crafted push URL can make the server sign a token for a push service other than the one the request is sent to.
+  - `Email/import` rejects a `blobId` that refers to a `Blob/upload` creation id in the same request (`"#u0"`) with `Invalid blob id.`.
+  - `Email/set` with a full `mailboxIds` object identical to the current mailboxes, together with a keyword change, stores the message with IMAP UID 0, so IMAP clients stop seeing it.
+- MTA:
+  - A node without the `outboundMta` role stops replying to `DATA` and to JMAP submissions once about 1024 messages have been queued on it.
+  - MX records are resolved through the DNSSEC-validating resolver even when DANE is disabled.
+  - A `DATA` stage Sieve script does not see headers added by milters or MTA hooks, and discards every milter and MTA hook change when it edits the message.
+- MySQL: Range deletions and search index removals start with a single unbounded `DELETE` and switch to chunks only after a timeout.
+- IMAP: `COPY` and `MOVE` fail with `NO [CONTACTADMIN]` when another session changes the same message at the same time.
+- Autodiscover: Implicit TLS ports (993, 995, 465) are advertised with `<Encryption>TLS</Encryption>`, which Outlook reads as STARTTLS.
+- HTTP: Idle keep-alive connections are never closed.

+//! The compliance roles (personal-data catalog spec, §7; settled
+//! 2026-09-28): a server-level Compliance Officer, and one Compliance
+//! Officer role in each tenant. A tenant's accounts can hold only roles of
+//! their own tenant (MT-3), so the tenant role is made per tenant: once for
+//! each tenant a server already has, and whenever a tenant is created.
+//!
+//! Each creation is recorded under `P` `c` in the fork's subspace, so a
+//! role an administrator deletes stays deleted. A tenant's role, while
+//! nobody holds it, is removed with the tenant so it doesn't block the
+//! delete.
+//!
+//! Both read what compliance work needs and change no server setting. The
+//! server-level officer also places, widens, releases and exports legal
+//! holds: that is the job, and each is audited with its reason. A tenant's
+//! role has no holds, which are server-level only (LH-13), and the tenant
+//! ceiling keeps it within the tenant. Each role carries a user's own
+//! permissions too (signing in, mail), since roles given to a person replace
+//! the default user role, and a tenant's accounts can't hold the
+//! server-level User role.
