`any_priv_below()` checks if a given AuthId has any given privileges
on a sub-tree of the AclTree. to do so, it first takes into account
propagating privileges on the path itself and then uses a depth-first
search to check if any of the provided privileges are set on any
node of the sub-tree pointed to by the path.

We got the digest available anyway, and it's only 16 bytes more to
save (compared to last_generation and the recently removed last_time,
both being 64 bit = 8 bytes each)
Side benefit, we detect config changes made manually (e.g., `vim
datacenter.cfg`) immediately.
Note that we could restructure the maintenance mode checking to only
be done after checking if there's a cached datastore, in which case
using the generation could make sense to decide if we need to re-load
it again before blindly loading the config anyway. As that's not only
some (not exactly hard but not really trivial like a typo fix either)
restructuring work but also means we'd lose the "detect manual
changes" again I'd rather keep using the digest.

to avoid the problematic open fresh datastore with fresh chunkstore
with, and that's the actual problematic part, fresh process locker.
As the latter uses posix record locks which are pretty dangreous as
they operate on a path level (not FD level) and thus closing any file
opened (even if it wasn't opened for locking at all) drops all active
locks on the same file on completely unrelated file descriptors -.-
Also, no operation wasn't exactly correct for this thing in the first
place, but we cannot use Operation::Lookup either, as we're currently
indeed using a rather stupid-simple way and *are* reading.
So until we optimize this to allow querying the AclTree if there's
any priv XYZ below a path, use the Operation::Read.

When re-opening a datastore due to the cached entry being stale
(config change) but also if the last re-open was >60s ago). On
datastore open the chunk store was also re-opened, which in turn
creates a new ProcessLocker, loosing any existing shared lock which
can cause conflicts between long running (24h+) backups and GC.
To fix this, reuse the existing ChunkStore, and thus its
ProcessLocker, when creating a up-to-date datastore instance on
lookup, since only the datastore config should be reloaded. This is
fine as the ChunkStore path is not updatable over our API.
This was always a potential issue but got exposed in practice by
commit 118deb4db8 which introduced the
unconditional "re-open after 60s" mechanism.

setting scrollable on the parent tab panel makes not much sense and
will always add a scroll bar that can scroll a few pixels, even if
there's enough space.
Rather set it to true (= auto) in the actual panels that hold the
content.
Also set a bottom margin so that users can see the "end" of the panel
at the bottom, otherwise it looked like it had a start and sides, but
no bottom.

input panel collect all form fields below them, so nesting two
input panels needs a bit of special care to avoid that each of the
panels adds the data of the deeper nested ones, resulting in
duplicate parameters that the backend then chokes one.

the intra-panel margin is still the same (10 + 0 == 7 + 3) but one

Fix missing load on initial view, re-use the prune input panel for
editing and avoid using a tab panel for a single tab, rework also
some columns widths and various other small parts-
