This enhances readability in sidebar, especially for "User’s Manual" and
"Protocol" pages

Fixes building with GCC 12.

With large "max_playlist_length" settings, the "data" array can be
very large, and initializing it during MPD startup causes page faults,
resulting in allocation of physical RAM.  This commit postpones the
initialization until the queue is really large, to avoid wasting
memory.

clang-tidy reports this is trivially copyable and thus std::move has no
effect.

SonarLint reports the latter to be better:

std::scoped_lock basically provides the same feature as std::lock_guard,
but is more generic: It can lock several mutexes at the same time, with a
deadlock prevention mechanism (see {rule:cpp:S5524}). The equivalent code
to perform simultaneous locking with std::lock_guard is significantly more
complex. Therefore, it is simpler to use std::scoped_lock all the time,
even when locking only one mutex (there will be no performance impact).
