v1.2.0: fix critical response format bug (18/18 endpoints passing)

Root cause: createApiRoutes() parameter shift
- Function signature was (app, jsonResponse, jsonError)
- Called from server.js as apiRoutes(jsonResponse, jsonError)
- All params shifted: jsonResponse→jsonError, jsonError→undefined
- Every success response returned {success: false, message: data}
- Health worked because it used res.json() directly

Fix: Removed unused 'app' parameter from createApiRoutes()
All 18 endpoints now return {success: true, results: data}

+## v1.2.0
+- Fixed critical response format bug: all endpoints now return {success: true, results: data}
+- Root cause: createApiRoutes() had (app, jsonResponse, jsonError) but was called with (jsonResponse, jsonError), shifting all params
+- Every jsonResponse() call was actually calling jsonError(), returning {success: false, message: data}
+- Health endpoint worked because it used res.json() directly, bypassing the wrapper
+- All 18 endpoints verified working: health, stats, search, suggestions, filter, trending, popular, upcoming, recent, spotlight, schedule, info, characters, relations, recommendations, episodes, watch
