[byteful]

Confidence Score: 4/5

This PR has one contained analytics response regression to fix before merging.

The functional changes are narrow, but AnalyticsService changes a client-visible date format for daily chart data.

T-Rex Logs

What T-Rex did

• I added a focused JUnit harness that mocks AnalyticsMongoRepository to return dailyTickets bucket id 2026-03-12 and asserted the service should expose Mar 12.
• I attempted to run the narrow Gradle test command, but execution was blocked because no java command was in PATH and JAVA_HOME was unset.
• I documented environment blockers from logs, including java not found and JAVA_HOME being empty, and Gradle wrapper abort messages.
• I captured and prepared six artifacts (three from the harness attempt and three environment logs) for reviewer inspection.

src/main/java/gg/modl/backend/database/mongo/repository/AnalyticsMongoRepository.java	Adds Mongo date-type filters before date aggregation to skip malformed date values; repository-layer placement is appropriate.

**Preserve chart labels**
The analytics API now returns raw aggregation keys like `2026-03-12` instead of the previous `MMM dd` labels for date-based chart series. This affects `dailyTickets` here and the same changed mapping for `dailyPunishments` and `newPlayersTrend`, so existing panel/minecraft clients that render these fields as display labels will show the wrong format after this hotfix.
