Fixes TwiN#1657 Previously, UpdateLastFileModTime() set the last file modification time to time.Now(). In containerized environments with volume mounts (e.g. Kubernetes, Google Cloud Run), the mounted file's timestamp can be in the future relative to the container's internal clock. This caused the configuration watcher to continuously evaluate that the file had been modified (because config.lastFileModTime < fileInfo.ModTime()), triggering infinite restart loops and effectively disabling the alerting engine. This commit updates UpdateLastFileModTime() to read the actual ModTime of the config file using os.Stat (and if it is a directory, using the newest ModTime inside that directory). It falls back to time.Now() only if the true modification time cannot be determined.
