Fix watcher timestamp handling for reused categorized runs

- interpret ATVM controller log timestamps in the controller's local timezone before converting to UTC so the watcher uses the correct current-run window
- prevent newly started categorized runs from immediately picking up older categorized artifacts just because the parent build name was reused
- keep the categorized watcher focused on artifacts from the current controller run instead of stale prior attempts
