FN-5897: surface linked goals in mission read paths

Expose mission-linked goals across mission detail surfaces.

- load linked goal records into mission hierarchy reads in core and return them from the mission detail API
- show linked goals in mission detail views, add goal-chip navigation, and anchor highlighted goal cards in GoalsView
- extend CLI mission output, docs, tests, and add a published changeset for the new read-path support
