feat: let the operator pause and resume a root's indexing (MNP 6.2)

A whole-root walk now checks its root before every file: removed or
ejected, it stops instead of reading the drive to the end; paused, it
finishes from the hash cache alone. A paused root is not watched, not
swept by reconcile and survives a restart (roster), its indexed files
stay served. Resume runs the reconcile sweep over the root, so entries
and their enrichment are kept.

Signed root_pause / root_resume over MNP, loopback routes, CLI
`root pause|resume`, a pause button on the indexing dock and
pause/resume in the roots table of Group settings.
