Jason 3d0ee50999 fix(fpga): reset chirp_counter at DONE; source CHIRP_MAX from radar_params ...

C-3: plfm_chirp_controller_enhanced never reset chirp_counter when the
frame completed. Counter sat at CHIRP_MAX after frame 1, so the
LONG_LISTEN -> GUARD transition guard (== CHIRP_MAX/2-1) never matched
correctly on subsequent frames and frame 2+ ran extra chirps until the
6-bit counter wrapped. Reset chirp_counter in the DONE state.

S-2: Replace hardcoded CHIRP_MAX = 32 with RP_CHIRPS_PER_FRAME from
radar_params.vh so the TX FSM tracks the single source of truth.

S-1: Correct misleading labels in tb_system_e2e G14.1-G14.3. Per
radar_params.vh the range_mode encoding is 2'b00 = 3 km, 2'b01 =
long-range, 2'b10/2'b11 = reserved. The TB strings previously called
2'b01 "short" and 2'b10 "long", which is inverted and inconsistent
with the RTL comments in radar_mode_controller.v.

Regression: 32/32 PASS.
