fix: epmConfigRoot() doesn't find EPM configs when packaged installer stages them under ProgramData/epm_configs instead of a bin-relative configurations folder

epmConfigRoot() (added on main to replace the old hardcoded
applicationDataPath()-based path) only checks for a configurations/
folder walking up from the binary directory. The Alpaca QIK package
stages EPM's .ccnf files under %ProgramData%/Qualcomm/<Product>/epm_configs/
instead, so on a QIK-installed package the platform combo box and
channel table in EPM.exe/EPMConfigurationEditor.exe/etc. are empty
(<select a config file>) and the SPM Version/platform info panel never
gets populated.

Added ProgramData/epm_configs fallback candidates (checked for both
Alpaca and QEPM branded installs) before falling back to the original
bin-relative default.
