Adds both settings to docs/cli_commands.md in the existing format, and records
the R8 dashboard, display controls and the two hardware fixes in the changelog.
The display.flip entry calls out that it is persisted config which survives a
firmware update, since a node still carrying flip=1 from testing looks exactly
like a firmware whose orientation was never fixed.
Port the observer doc cleanup from observer-firmware (4beb5472) onto dev,
keeping dev-specific content intact.
- move internal mechanics into MQTT_INTERNALS.md: deferred construction,
runtime slot memory, backoff/circuit breaker, message building, command
namespacing, and the legacy prefs key mapping
- drop the duplicated First-Time Setup, Command Architecture, and SNMP
Monitoring sections, folding their unique steps into Quick Start
- condense the partition/NVS prose and merge the five custom-broker
examples into one Custom Brokers section
- promote the preset list to a top-level Broker Presets section with an
Extra setup column, and document the presets the table was missing:
meshcore-fi, corecomms, mesh-chaun14, wcmesh, and meshtexas
- fix the coloradomesh port (443, not 1883)
- point flasher and changelog links at observer.gessaman.com
- restore the nbr: status field, which the code still emits, and correct
the neighbors topic to QoS 0 retained per allow_retain
Dev-specific content is preserved as-is: per-slot packet filters, the Web
Configuration Portal, local testing without hardware, MeshRank's raw
exclusion, and neighbors default_scope.
