HamTabv1

Scaffold a new HamTabV1 dashboard widget end-to-end — registration, HTML, JS module, styles, feature flag, mandatory docs, and the matching mobile WidgetDefinition.swift entry. Use when the user asks to add/create a new widget (panel, card, gauge, list) to the HamTab dashboard.

Sync HamTabV1 deployment branches — merge `main` into `lanmode` and `hostedmode` with the mandatory pre-merge divergence check and post-merge validation. Use when the user says "sync branches", after committing shared code changes to `main`, or before a release. NOT for docs-only changes.
