Pull request overview

Moves the tray-mode configuration file into the per-user config directory (aligned with where the embedded SQLite DB lives) and adds a one-time migration path so installer-provisioned credentials carry over on first tray launch.

Changes:

• Update config-path resolution so tray mode prefers <UserConfigDir>/device-management-toolkit/config.yml, otherwise fall back beside the binary.
• Add seedConfig to copy an installer-provisioned config into the per-user location on first tray run.
• Add unit tests covering config path resolution and seeding behavior.

@sudhir-intc This is for the installers, at present config file will be in the app’s install folder, which anyone could read. Now it’s stored securely in each user’s own space. I link this PR to #870

tested on linux, results look good

both user config path and machine config path are not exist

• user config path generated with correct permission

user config path exist, but machine config path not exist

• user config path reused without generate
