Graham McIntire af08e72816 polish(aprs): consolidate callsign regex, document raise, note negative-sample v1 limit ... - Extract PathParser.valid_callsign?/1 and reuse from the calibration Mix task instead of duplicating the regex. - Document raise behavior on Aprs.recent_packets_with_paths/1 and Aprs.station_positions/1 (already noted in moduledoc; @doc reinforces for callers reading the function head). - Note in the BandConfig guard comment why it sits before the Oban pause (so a misconfig exits without leaving queues paused). - Reword the band-mismatched-negatives note as a v1 limitation (no TODO tag — codebase convention is zero TODOs).		2026-05-01 13:10:57 -05:00
