/api/steam/test/{steamId} let anyone query any Steam profile with our API key. /internal/** had no controller but was open for any future one. Actuator now exposes only health, without details. The management block was also indented under endpoints, so show-details never applied.
Introduce SteamOwnedGamesResponse and SteamProfileAndGamesResponse DTOs and extend SteamApiService with getOwnedGames(...) and getFullPlayerProfile(...) to fetch and combine player summary and owned games. Update SteamTestController to return the combined profile/games response. Remove redundant Steam service URL entries from application.yml. Add SteamApiServiceTest to cover player summary, owned games (including null fields), and the combined profile flow; service falls back to empty lists on errors.
Introduce Steam integration: add SteamClientConfig (RestClient bean), SteamApiService (calls GetPlayerSummaries and returns a Player DTO), SteamPlayerSummaryResponse DTO, and SteamTestController (/api/steam/test/{steamId}) for quick testing. Update SecurityConfig to permit the test endpoint and adjust the SecurityFilterChain bean signature. Add Steam API settings: base-url in application.yml and a dev API key in application-dev.yml. Includes basic error logging and optional response handling when no player is found.
Add project bootstrap for build, CI/CD, and local development. Introduces Maven Wrapper (mvnw, mvnw.cmd, .mvn/wrapper), multi-stage Dockerfile, docker-compose files (compose.yaml, docker-compose.dev.yml), .env, banner and README. Adds Gitea Actions workflow to build, test and push container images. Update application.yml (port -> 8090, virtual threads, API versioning, management/actuator/prometheus settings, Steam API config) and add application-dev.yml for local overrides. Extend pom.xml with caching, observability (actuator, micrometer/prometheus), testing/dev dependencies (testcontainers, devtools, additional spring test modules) to support CI and local testing.
