feat: add oom_score_adj to all AIO containers

[Copilot]

Sets oom_score_adj on all AIO containers so the Linux OOM killer targets less critical containers first under memory pressure. The default for containers without an explicit value is 500, placing them slightly above typical host processes. Values are assigned by priority tier:

• -300: database, redis, borgbackup, watchtower (most protected)
• -100: apache, nextcloud
• +100: notify-push, harp, docker-socket-proxy
• +300: all remaining containers (collabora, talk, talk-recording, clamav, onlyoffice, imaginary, fulltextsearch, whiteboard, domaincheck)
• +500: default for any container without an explicit value

Changes Made

• containers.json: oom_score_adj values set on all 18 containers according to the tiers above.
• containers-schema.json: Added oom_score_adj as an integer property with minimum: -1000 and maximum: 1000.
• Container.php: New public int $oomScoreAdj property.
• ContainerDefinitionFetcher.php: Parses oom_score_adj from JSON and assigns it directly; default is 500 when not specified.
• DockerActionManager.php: Sets HostConfig.OomScoreAdj during CreateContainer(); skipped when value is 0.

same here, I don't see any reasons why the nextcloud AIO containers should be more important then my other containers on my host. Maybe give important containers a small boost and don't change the default of the other containers, but these values are far from is acceptable. To work against this I would need to change the values for all my important running processes like my mail server. Otherwise my postfix or the reverse proxy could be killed to safe collabora or elasticsearch

@copilot please change default in ContainersDefinitionFetcher to 500 instead of 0 and adjust the all added values by +500

Done in 46949e8. Default is now 500, and all container values are shifted by +500 (e.g. database/redis/borgbackup/watchtower: -300, apache/nextcloud: -100, notify-push/harp/docker-socket-proxy: +100, remaining: +300).

@Zoey2936 what do you think about this solution?
