refactor: Refactor lockfile names for consistency and clarity

- Renamed "${lockdir}/${selfname}-laststart.lock" to "${lockdir}/${selfname}-last-started.lock"
- Renamed "${lockdir}/backup.lock" to "${lockdir}/stopping.lock"
- Renamed "${lockdir}/${selfname}-start.lock" to "${lockdir}/${selfname}-started.lock"
- Renamed "${lockdir}/${selfname}-starting.lock" to "${lockdir}/${selfname}-stopping.lock"

This commit refactors the lockfile names in the codebase for better consistency and clarity. The changes make it easier to understand the purpose of each lockfile and improve readability.
