Ensure that when viewing a specific callsign (e.g., /w5isp), the most
recent position packet is always displayed, regardless of how old it is
or what historical time period is selected.
The fix ensures that during historical loading, if we're tracking a
specific callsign and it's the first batch, we always include the
callsign's most recent packet even if it falls outside the selected
historical time filter (1h, 3h, 6h, etc.).
This resolves the issue where callsigns with very old last positions
would not be visible when viewing their specific page.
