Fixes node-26#11. OP25's generated config said "rtl" (= whichever dongle
enumerates first), so on 2-SDR nodes a decoder could take OP25's dongle
and stop recording. Now:
- sdr_pins: {op25|adsb|ais: serial}, absent = automatic. Every OP25
config generation (op25_client.generate_config) rewrites the device to
rtl=<serial>: the pin, else the first dongle's serial, which is what
"rtl" always opened. Left as "rtl" only for unknown/shared serials.
- secondary-sdr: /secondary/devices lists dongles + serials via librtlsdr
(works while claimed). apply(priority, pins, reserved) never touches
OP25's dongle, gives a pinned service only its own dongle, lets a
higher-priority service take a spare from a lower one, and still runs a
pinned lower-priority service when the top pick has no dongle.
- sdr_settings.py replaces secondary_priority.py: one apply path for the
local dashboard, the new set_sdr_config C2 command (set_secondary_priority
kept as an alias) and config pushes. OP25 restarts only when its own
dongle changes. Checkin reports sdr_devices, sdr_pins, op25_sdr_serial.
- Local dashboard: 'SDRs' card with an OP25 SDR dropdown and a per-service
dongle dropdown, duplicate-serial and double-pin warnings.
Verified: edge-node pytest 194 passed; secondary-sdr tests 7 passed;
flake8 clean; page JS passes node --check.

QA blocker: a reordered but unsaved list still showed the old order's
decoder as 'Running'. Also shows 'Unknown' rather than 'Waiting for SDR'
when the secondary-sdr service doesn't answer (server-26#187).

Replaces the single secondary_sdr_mode with secondary_sdr_priority, e.g.
["adsb", "ais"]. OP25 always keeps its own dongle; the secondary-sdr
container starts decoders top-down until it runs out of free SDRs, so a
3-SDR node runs ADS-B and AIS at once and a 2-SDR node runs the top pick.
- secondary-sdr: one decoder per mode, POST /secondary/apply(priority)
(no-op when the right prefix is already running), orphaned decoders
from a uvicorn reload are reaped on start, /status reports sdr_count
via lsusb (op25's :stable image has none).
- edge-node: one apply path (set_secondary_priority) for the local
dashboard, a new C2 'set_secondary_priority' MQTT command, and config
pushes; it never restarts op25. Legacy mode migrates on load. Checkin
reports priority, what's running, and sdr_count. Uplink forwards
aircraft and vessels whenever either is present.
- Local dashboard: 'Secondary SDRs' card to enable/reorder/save.
Verified: edge-node pytest 190 passed, flake8 clean.

Two unauthenticated surfaces closed on the edge node.
Dashboard and API: the local dashboard and every /api/* route were open to
anything on the node's LAN. Adds a login page plus session-cookie auth for
the browser, and cookie-or-Basic for the API so scripted callers stay
possible. Passwords are hashed with stdlib scrypt (no new dependency, this
runs on a Pi) and compared in constant time; the salt and session-signing
secret persist in credentials.json. Startup warns while the default password
is still in place. No non-browser callers of the node API exist today
(C2 talks to nodes over MQTT and nodes call C2 outbound), so nothing breaks.
Adds python-multipart, which FastAPI's Form() needs for the login POST and
which was missing from requirements entirely.
MQTT: nodes authenticated with a shared drb-node password, and the broker
ACL keyed off %c — the client-supplied client id — so any holder of that one
password could claim another node's topic namespace. Nodes now connect as
username=<node_id>, password=<their C2-issued api_key>, which mosquitto's
dynamic-security plugin checks, with the ACL keyed off the authenticated %u.
TLS is gated on MQTT_TLS and uses default CA verification.
The old key_request MQTT path stays in place behind TODO(mqtt-cutover)
markers as the fallback until the cutover is proven; a node with no api_key
on disk logs a clear repeated refusal rather than spinning.
