Fix mount point ordering consistency

- Sort filesystems by mount point in disk collector for consistent display
- Sort tmpfs mounts by mount point in memory collector
- Eliminates random swapping of / and /boot order between refreshes
- Eliminates random swapping of tmpfs mount order in RAM section

Ensures predictable, alphabetical ordering for all mount points.
