- Replaced pass-by-value std::string parameters with const std::string&
or std::string_view to prevent SSO overallocations.
- Refactored static mapping functions in UPower to return
std::string_view instead of constructing std::string literals, enabling
perfect cache locality.
- Optimized string concatenation in hot loops (network IPs, inhibitor
lists, sway window marks) by using std::string::append() and
pre-reserving capacity instead of overloaded operator+ which produces
temporary heap instances.
These optimizations reduce high-frequency memory churn and overall heap
fragmentation within the main rendering loops.

While looping over all the upower devices, the currently set device that will be rendered in the waybar, is overridden. Since the loop doesn't end when the device is found, the upDevice_ is overridden with NULL in the iteration for the next device.
Now we only override upDevice_ if the current device matches the constraints.
