refactor(dbus): Parameterize picontrol_device and config_rsc

Replaced hardcoded paths with configurable parameters `picontrol_device`
and `config_rsc` across multiple classes. This improves flexibility,
making the components adaptable to various environments or setups.
Updated corresponding initialization and method implementations to use
these parameters.
