- update, files and the 6 /api catalog controllers now live in the engine on
a new WarpEngine::ApiController base (same rescue/mime behavior as host)
- engine routes serve /update, /file/*path, /api/software*, /api/builds*,
/api/image/:id, /api/download at unchanged public paths via the root mount;
host routes keep only TTG endpoints (events, members, wiki, rss, swagger)
- /update secret comes from WarpEngine.config.update_secret and an
unconfigured secret now rejects every request (previously an empty
UPDATE_SECRET env accepted empty secrets)
- apipie-rails is an engine dependency (DSL in engine controllers); dummy app
configures apipie with validation off, mirroring the host
- engine request specs: catalog controller specs moved from host plus new
/update auth contract spec
Verified: engine suite 53 green, host suite 6 green, /api/software and
/api/builds byte-identical to baselines, /update 401/400 behavior intact,
admin and TTG endpoints OK.
