fix(dial): debounce dial pulse to drop contact bounce edges

Each real rotary pulse was registering 5-7 times because the dial's
mechanical contact bounces for a few ms on each open/close. Dialing
"4" produced 26 pulses, which then fell through as invalid.

Add a 25 ms debounce window in DialReader._on_pulse: subsequent edges
within that window of the previous accepted pulse are dropped. Real
rotary pulses arrive at ~100 ms intervals so there's a wide margin.

Tunable via timing.pulse_debounce in config.yml if a particular dial
has a different bounce characteristic.
