[feat](trx-frontend-http): intercept freq/mode changes for virtual channels

When on a non-primary (virtual) channel, redirect freq and mode changes to the channel metadata API instead of the server: - vchan.js: add vchanIsOnVirtual(), vchanSetChannelFreq/Mode(); expose window.vchanInterceptMode() hook; wrap window.setRigFrequency so all callers (jog, freq input, bookmarks, spectrum click) are automatically redirected without modification - app.js: check vchanInterceptMode() in applyModeFromPicker() before posting /set_mode - bookmarks.js: check vchanInterceptMode() for mode in bmApply(); setRigFrequency() redirect is automatic via the vchan.js wrapper; bandwidth and decoder toggles still apply regardless of channel Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> Signed-off-by: Stan Grams <sjg@haxx.space>
