release: 1.3.0: 1.3.0-1.3.1: security pass, queue persist, full backup layout

[1.3.0]
Security and quality after 1.2.5: domain-admin send-log authorization, fail-closed sign-in and application delete, level-2 rate-limit race fix, restore Resync, expanded tests, operator docs, release CI, and OFL for IBM Plex. Upgrading from 1.2.x is a tag bump; no migration.
Added:
  - licence: the SIL Open Font License 1.1 text now travels with the IBM Plex
  - docs: agreed roadmap item **queue-retries** — show this Postfix's retry
Security:
  - The independent security review of the send-log authorization and
Fixed:
  - test (e2e): send-log status scrapers follow the badge markup in
  - security (panel): the Deliveries list is scoped to a domain administrator's
  - mail (level-2 rate limit): the ceiling is no longer overshot by messages that
  - panel (sign-in): a session that cannot be written to the database no longer
  - panel (applications): deleting an application removes its SASL credentials
  … (2 more in CHANGELOG)
Changed:
  - docs: operator and as-built docs aligned with the code after a full
  - docs: [guide.md](docs/guide.md) reorganised into **Installation**, **Instance
  - docs: the 2026-08-13 full-tree review plan is complete — every phase (P0–P7)
  - licence: [NOTICE](NOTICE) tells modifiers to update `SourceURL` in
  - ci: the release image is published only for a **published** GitHub Release
  … (9 more in CHANGELOG)
[1.3.1]
Retry policy in the panel, persistent Postfix queue, and self-contained full backups. Mail queue and delivery history show this Postfix's first retry, backoff cap, and queue lifetime. Deferred mail survives container recreate. Full backups now archive `data/`, compose, `.env`, and `certs/`; the archive layout breaks 1.3.0 flat backups (unpack those with `tar xzf backup.tar.gz -C ./data` as before). Upgrading from 1.3.0 is a tag bump; no schema migration.
Added:
  - Mail queue and a delivery's history show this Postfix's retry policy
  - docs: **Plan checklists** in [development.md](docs/development.md) — format,

  - docs: roadmap candidates **send-log-retention** (panel Settings for delivery
