Fix both pool-level and filesystem metric parsing bugs

1. Prevent filesystem _fs_ metrics from overwriting pool totals
2. Fix filesystem name extraction to properly parse boot/root names

This resolves both the pool total display (showing 0.1GB instead of 220GB)
and individual filesystem display (showing —% —GB/—GB).
