The Details button currently opens a second page showing the quest description again. This change adds an optional details field for separate, additional information.

Changes

• Keep description on the overview and show details on a separate page with only Back, returning to the overview.
• Hide the Details button when the optional text is absent or empty; never repeat the description as a fallback. Preserve existing visibility/open-by-default settings.
• Support text components and translation keys, serialization and client synchronization.
• Add Details directly below Description in the in-game editor; emptying it removes the optional field.
• Use Questlog scrollbar textures for both fields, with independent wheel scrolling and scrollbar dragging. Keep parent-panel scrolling and mouse release working.
• Document the field, /questlog edit_mode true, empty values and editor controls; include a quest example.

Existing per-quest panel sizes and prerequisite behavior are preserved.

Validation

• 35 automated details checks and 18 headless editor-scrolling checks passed.
• Manual checks covered different/absent/empty details, navigation, editor saving/clearing, and text-field scrolling. The contributor confirmed the final editor correction in game.
• Gradle compilation/build checks passed for Minecraft 1.21.1 / NeoForge and Fabric.
• The latest combined test build was manually validated by the contributor on NeoForge 1.21.1; matching functionality also passed on Forge and Fabric 1.20.1. Gameplay validation used the combined build, rather than each isolated PR branch.
• Fabric 1.21.1 was build-checked but has not been tested in game.
• Headless checks do not verify rendered UI; visual/gameplay results above are manual. Multiplayer has not been validated.

This contribution was prepared with AI assistance; the contributor performed the gameplay tests. Each new feature PR is based directly on its matching upstream Minecraft branch and can be accepted independently.
