fix(botfights): correct data_uid to 999 (actual image UID, not 1001)

The prior fix (5745db51) copied the fedimint-clientd/barkd data_uid
pattern (1001) without verifying it against this image. Live on
x250-beta the container still crash-looped with the same SqliteError:
unable to open database file — `podman exec botfights id` showed
uid=999(botfights) gid=999(botfights), not 1001. The image's
Dockerfile does `useradd --system` with no explicit UID, which lands
at 999, and security.user in the manifest is descriptive only — it is
not read by this app's (non-Quadlet) install path, so it can't be used
as the source of truth either.

Fixed data_uid to 999:999 and corrected security.user to 999 to match
reality. Verified live: manually re-chowned the existing bind mount to
999:999 on x250-beta, restarted the container, confirmed
`database migrated` + `listening on http://localhost:9100` +
`/api/health` returns ok, and confirmed /api/bots on x250-beta returns
identical data to the canonical arena (arena-proxy forwarding
correctly). Regenerated catalog; cargo test -p archipelago-container
manifest passes (38/38).
