Pocsag UX Revamp (#1408 )

* Set bandwidth_filter in pogsac * WIP pocsag UI revamp * Settings UI, better console, UI Revamp * Add baud rate to error messages * Reset last_addr in error cases * Show malformed messages as different color vs hiding * Use light grey to indicate low quality decode --------- Co-authored-by: kallanreed <kallanreed@noreply.github.com>
