- OTA_CHANNEL_TAG is now 'beta-dev', so the embedded version carries the
channel AND its provenance: v1.16.0.N-observer-beta-dev-<hash>. This channel
is built from the upstream-dev-merged line, so 'dev' is visible in `ver`,
the MQTT firmware_version, and SNMP rather than inferred from a branch name.
Verified on a real build; OTA version parsing is unaffected.
- config-beta.json is now written into the flasher checkout and committed,
reversing the earlier ephemeral approach: the flasher SPA loads it directly
for ?config=config-beta, so it has to be served. It is still DERIVED from
config.json on every beta build rather than hand-maintained, so the dev/beta
device list cannot drift from production.
