[fix](trx-frontend-http): gate APRS bar to PKT mode, reject CRC failures

- Hide bar whenever mode != PKT; app.js calls window.updateAprsBar()
  on every server-pushed mode change so the bar disappears immediately
- CRC-failed frames are excluded from the bar (both live and history
  restore); the [CRC] rendering path is removed
- Offset bar 1.2 rem from left edge for visual breathing room
