fix: Update system-level branding in PiPedalCommon (hotspot/ALSA names, service group, device name)

- WifiConfigSettings.hpp: default hotspot 'pipedal' -> 'op-pedal'
- WifiDirectConfigSettings.hpp: default hotspot 'pipedal' -> 'op-pedal'
- WifiDirectConfigSettings.cpp: default device name 'PiPedal' -> 'OP-Pedal'
- ServiceConfiguration.hpp: deviceName 'PiPedal' -> 'OP-Pedal'
- ServiceConfiguration.cpp: group name 'pipedal_d' -> 'oppedal_d'
- AlsaSequencer.cpp: ALSA client/port/queue names 'PiPedal' -> 'OP-Pedal' (5 occurrences)
