refactor: deduplicate hrrr download, simplify radio/mqtt, fix credo/perf issues

- hrrr_client: extract shared fetch_grib_ranges/2 to eliminate ~80% duplicated code
- mqtt: encode_varint/1 uses IO list accumulator instead of O(n^2) binary concat
- commercial: single-pass reduce for aggregate_degradation, remove unused average/1
- scorer: single-pass reduce for safe_avg and build_path_conditions
- terrain_analysis: split 76-line do_analyse/4 into 3 focused functions
- radio: build_position_changes/3 simplified from then-chains to Enum.reduce
- recalibrator_test: fix credo warning (length > 0 -> != [])

refactor(pskr): drop emqtt, talk MQTT 3.1.1 over :gen_tcp directly

emqtt's transitive `quicer` dep needs CMake + msquic submodule
clones to build, which the slim Debian builder image doesn't ship —
the prod CI build was failing inside `mix deps.compile`. Tortoise311
is the obvious pure-Elixir alternative but it bundles a
gen_state_machine + retry/inflight stack we don't use because we're
subscribe-only at QoS 0.

Implementing the wire protocol inline is ~150 lines in
`Microwaveprop.Pskr.Mqtt` (CONNECT/SUBSCRIBE/PINGREQ/DISCONNECT
builders, CONNACK/PUBLISH/SUBACK/PINGRESP parser, varint codec).
Pskr.Client now uses :gen_tcp with `active: :once` framing,
buffers partial reads, schedules its own keepalive, and parses
inbound packets in a tight loop.

Drops `BUILD_WITHOUT_QUIC=1` from the Dockerfile — no longer
relevant since there's no native dep at all in the build chain
now.
