chore(images): refresh every registry pin to current upstream digest

Container images re-resolved against their registries today; each pin is the
manifest-list digest the tag answers now, so no container is served from a
build that upstream has already replaced.

Version-tag moves: authentik 2026.8.3 -> 2026.8.5 (server/worker/outpost and
the ldap image, which now carries the tag instead of a bare digest so the pair
can never drift apart), seerr v3.4.1 -> v3.5.1, calibre 9.15.0 -> 9.17.0,
calibre-web 0.6.27-ls402 -> ls407, plex ls329 -> ls330, tautulli
v2.18.1-ls245 -> v2.18.2-ls250.

Digest-only moves inside the same stream: postgres 16-alpine, mariadb 11,
redis 7-alpine, valkey 9-alpine, grafana, alertmanager, gluetun, searxng,
open-webui, jellyfin, romm, chromedp/headless-shell, lightpanda/browser.

Rollback is the previous digest on the same Image= line.
