Fixed the sticky node name validator issue, where a validator used once was incorrectly reused for all input text dialogs. Added a new feature: the Inspector view now shows calculated routes for nets, including inactive ones.

* inspect-traces.js - PCB net trace generation, caching and rendering for the
* Inspect view, powered by the WireBender `PcbVisualizer` WASM API.
*
* Design notes
* ════════════
* - Traces are routed ONCE in a single reference-image coordinate space using
* one `PcbVisualizer.route()` call (for all nets initially). The resulting
* polylines are cached in memory keyed by net id.
* - Rendering on every other PCB photo reuses the existing perspective
* transform logic (homography projection) instead of recalculating traces
* per view. This keeps the cost flat even with ~12 simultaneous views.
* - The cache lives on the Inspector instance, so it survives navigation
* between tabs/views. Each net carries a content signature; when net data
* changes the affected entries are transparently recomputed.
