feat(core): make FlyToInterpolator globe-aware

[charlieforward9]

Summary

• make FlyToInterpolator use the active viewport when controllers can provide one
• keep the existing WebMercator flyToViewport behavior for normal map views
• interpolate GlobeView flights along a globe path while preserving the existing fly-to zoom curve in globe scale space
• add tests for antimeridian globe flights and globe zoom-scale continuity

Notes

This PR is based directly on master and is intentionally separate from #10307.

Verification

./node_modules/.bin/vitest run --project headless test/modules/core/transitions/fly-to-interpolator.spec.ts test/modules/core/controllers/controllers.spec.ts
./node_modules/.bin/tsc -p modules/core/tsconfig.json --noEmit --pretty false

Closing this for now. The existing FlyToInterpolator behavior is preferable to this projection-specific path, and this added more complexity than value.
