torlando-tech 90d5afa35b 15-tap half-band FIR anti-alias filter, reduce mic gain to 15dB

Replace crude 2-tap averaging with proper 15-tap half-band FIR filter
for 16kHz→8kHz decimation (~60dB stopband attenuation, Kaiser beta=6).
Exploits symmetry + half-band zeros for only 5 MACs per output sample.

Separate TDM deinterleave (CH0 extraction at 16kHz) from FIR decimation
for cleaner signal processing pipeline.

Reduce ES7210 mic gain from 8 (24dB) to 5 (15dB) to avoid ADC clipping;
AGC in the voice filter chain compensates for quieter input.
