* fix: accept NUL-padded RPTC callsigns in login check
Fixed-width RPTC fields may be padded with NUL (ipsc2hbp) or spaces
(MMDVM). str.rstrip() left trailing NULs so matching DB callsigns were
rejected with MSTNAK after a successful passphrase exchange.
* fix: strip NUL padding from RPTO OPTIONS in logs and storage
ipsc2hbp pads the fixed-width RPTO body with NULs; logs showed ^@ noise
and peer CALLSIGN as raw bytes on the options line. Normalize on ingest
and in redact_pass_in_options.
* fix: strip NUL padding from monitor export and shared HBP fields
Centralize fixed-width NUL/space trimming in domain helpers and use them
for dashboard_state peer fields, OPTIONS parsing, proxy self-service, and
remaining CALLSIGN log lines.
* fix: add shared PASS= redaction for OPTIONS log lines
Mask PASS= secrets in RPTO/OPTIONS logging to avoid leaking hotspot
passwords in log files.
* fix: rework self-service RPTO to distinguish PASS, empty, and OPTIONS
Three RPTO cases now handled explicitly:
- PASS=password: store hash, fetch OPTIONS from DB (unchanged)
- Empty payload: DB is the authority, fetch OPTIONS from DB
- OPTIONS with content: hotspot is the authority, pass through to master
When the hotspot does not send PASS, the stored password is cleared
(NULL) so only IP auto-login works — password login is impossible
with a NULL hash, matching the legacy dashboard proxy behaviour.
Also removes the noisy DEBUG log on RPTC ("not in mysql_option_peers")
that fired on every normal login, and adds clear_psswd action to the
MySQL repository for explicit NULL writes.
* fix: elevate proxy attach rejection to WARNING for RPTC/RPTO
Control commands (RPTC/RPTO) rejected by attach should be visible at
INFO level, not hidden behind a debug flag, since they indicate a peer
sending configuration before the login exchange completed.
* fix: remove noisy CALL RX log on OBP DMRE voice header
The log fired on every DMRE VHEAD packet from each OBP peer, producing
duplicate entries for the same stream (multiple OBP peers relay the
same call). The existing CALL RX logs for DMRD and OBP v0/v1 paths
already cover stream start diagnostics.
* fix: fetch DB options when hotspot sends no RPTO after RPTC
Some hotspots complete the RPTC (repeater configuration) step but never
send an RPTO packet, leaving the peer without any OPTIONS applied. The
legacy proxy used a 10s timer after RPTC to fetch OPTIONS from MySQL in
that case; restore that behaviour here.
When RPTC arrives and the peer is not already in _mysql_option_peers,
schedule a 10s fallback timer. If no RPTO arrives before it fires, treat
the peer the same as an empty RPTO (BD is the authority) and fetch
OPTIONS from MySQL. If an RPTO does arrive, the existing cancel paths
abort the timer.
