fix(import): address review on metadata, bounds, navigation, clock and GPX
- Imported metadata stays inert: descriptions, native labels, properties and KML extended data are dropped from every entity; names are kept as short plain text. GeoJSON loads with a describe that builds no HTML, and simplestyle (including marker-symbol) is dropped, so no icon asset is fetched for a file and GeoJSON draws in its row's color. - Bound geometry before loading: features and vertices are counted in the parsed GeoJSON, the KML document and while reading GPX, and a file over 20,000 features or 250,000 vertices is refused before Cesium builds it. - Imports run one batch at a time, so concurrent picks or drops cannot pass the 12-file cap. - Fly-to framing walks long tracks by index instead of spreading them into a call. - Fly-to is an immediate navigation through the application shell; the fly after an import is a deferred navigation stamped when the batch starts and re-asserted just before flying. - Dated imports never change the shared clock: imported sources expose no clock, entities are available for all time, and a KML gx:Track is drawn as its line. - GPX is read into GeoJSON with one line per track segment, without times. - KML/KMZ rows show a hatched swatch (they keep their own styles); keyboard focus is kept on the same control after hide/show and moves to the next row after remove. - Unit regressions for each, and the rendered QA now imports hostile metadata, dated KML/GPX and a two-segment track, and fails on any request for a file's contents or icon assets, a clock change, or surviving metadata.
