[feat](trx-frontend-http): add APRS bar overlay on overview strip

Browse Source 
Show the last 5 received APRS frames as a compact overlay in the
bottom-left corner of the waterfall strip, styled similarly to the
RDS PS overlay (backdrop blur, pill border). Frames fade out by
recency via CSS sibling-selector opacity steps. Bar auto-hides when
empty and is cleared by the APRS clear button. Restored from
localStorage on page load.
