[pending-judge] feat(deploys): catalog deploy via shipdeck bridge (DC-CATALOG-3)

GET /deploys/catalog/apps -> bridge /api/catalog/apps (73 embedded apps,
single source of truth). POST /deploys/catalog/deploy {app,port,env} ->
validated (service-id charset, port 1024-65535, env name/value rules) then
proxied to bridge /api/catalog/deploy which runs the shipdeck CLI catalog
deploy (OCI image -> hardened systemd service; NO Docker daemon). Audited
as deploy.catalog with ok/seconds. 11 table-driven route tests incl.
validation rejections never reaching the bridge + bridge-failure 502 shape.
App Selector submit rewired from /apps/deploy (Docker chain) to
/deploys/catalog/deploy — same modal, same fields (port, mediaPath, plex
claim token as env), no new UI screens. Full suite 3510/3510 (156 suites).
