Remediation recommended

1. Servo timer capacity reduced 🐞 Bug ≡ Correctness

On ATOMRCF405MINI and ATOMRCF405NAVI, moving S4 to TIM3 causes a 4-motor setup to claim TIM3 for
motors, which blocks S8 (also on TIM3) from being allocated as a servo output. This reduces the
remaining servo outputs after allocating 4 motors and can trigger
PWM_INIT_ERROR_NOT_ENOUGH_SERVO_OUTPUTS for mixers requiring 4+ servos.
Agent Prompt 
## Issue description
ATOMRCF405MINI and ATOMRCF405NAVI changed S4 from TIM1_CH3N to TIM3_CH4 (same PB1 pin), but S8 is also on TIM3. In a typical 4-motor configuration, INAV assigns motors in `timerHardware[]` order and uses `pwmClaimTimer()` to apply motor usage to all channels on that timer, which makes S8 unusable for servo outputs; this reduces the available servo output count and can cause `PWM_INIT_ERROR_NOT_ENOUGH_SERVO_OUTPUTS` on servo-heavy mixers.

## Issue Context
- Targets affected: `ATOMRCF405MINI`, `ATOMRCF405NAVI`
- Change: S4 now uses `TIM3` while S8 already uses `TIM3`.
- Allocation rule: servos cannot share a timer with any motor output, and motor claiming propagates to all channels of the timer.
