Summary

• Ports the firmware-correct 16-slot Bosch-A object bank radar decoder (from night-star-bosch-radar, base commit + the vRel-authority fix that closes a raw-derivative-poisons-KF hazard) into radar_interface.py as a branch alongside Nidec — same pattern Nidec already uses, no delegate class.
• Wires it in for the full HONDA_BOSCH_A harness category (10 platforms: Civic Bosch, Civic Bosch Diesel, Accord, CR-V 5G, CR-V Hybrid, Acura RDX 3G, Insight, Honda e, Honda e Advance, N-Box), not just Civic Bosch.
• Gate lives in interface.py (this branch has no CarInterface extension-point layer to hook into), keyed on a new HondaBoschARadar param (default on).

Test plan

• 86/86 tests pass (opendbc/car/honda/tests/test_bosch_a_radar.py), verified locally on this branch's actual submodule commit
• On-road validation across the newly-enabled platforms (only Civic Bosch has been road-tested with this exact decoder so far)

Closing as already ported and superseded on the current development line. Thank you for the original Bosch-A radar work.

• The port is present in 0dae944. Comparing this PR with that port: the radar DBC is identical, and the decoder differs only in the CP_SP constructor adaptation; platform wiring and tests were adapted to the newer tree.
• Subsequent range-scale fixes and the newer parser in honda: port the current Bosch-A radar parser from Honda-PTM-Testing #3 are retained in nrdr-development, now at 427f198, which is also the exact submodule revision selected by Bosch-A longitudinal: all of Testing's Bosch-A tuning, always on openpilot#27.

This closes the obsolete PR targeting nrdr-bare; it does not claim the original commit was merged into that historical branch. Reapplying it to development would duplicate/replace newer work. No source changes were made during this reconciliation.
