feat(tgu-ops-ui): add spacecraft work editor tab

Port the TGU editor prototype into pcp-tgu-ops-ui as a new editor tab, add draft/conflict/pass logic with tests, extend the 2D map picking API, and include editor styles/theme aliases and task/prototype docs.

Validation: npm run test; npm run build in services/pcp-tgu-ops-ui.
