nzbget: placed config, the build ace runs, its password a file, its API provided

The manifest named /services/nzbget/config and /var/lib/mesh/nzbget/config.json,
host paths ADR 0112 takes out of definitions. The config dir is now pathless
(${dir:config}); the runtime's config and route binding live in a placed state dir.

The image is pinned to v26.0-ls233, the digest ace runs. The old pin (v26.3-ls261)
is newer but unproven against ace's queue; moving up is a later, separate step.

The password own-secret reached the tools and nothing else, so a fresh machine ran
nzbget's well-known default while the tools held a minted value that matched
nothing. The server now reads it too, through the image's FILE__NZBGET_PASS (a
path in the environment, the value from a 0600 root file - ADR 0086), and both
restart on it. An adopted machine accepts its existing ControlPassword.

The tools assumed the control user is "nzbget"; they now read ControlUsername
from nzbget.conf on the read-only config mount (ace's is not "nzbget").

sonarr, radarr, lidarr and bookshelf reached nzbget by container name on HAL's
shared network. nzbget now provides nzbget-api (node scope: a download client
must share the consumer's download spool) and serves scheme, port, url-base and
username; the password is the operator-accepted pair credential, as for #156.
The web endpoint is routed (label nzbget). The runtime dials ${port:6789}, the
same line as #154.

Verified: catalogue tests with MESH_CATALOGUE set (not skipped); rendered for ace
with a pinned port and username setting; a throwaway of the pinned image on a
fresh 0700 dir with the secret as a 0600 root file answered the secret (200),
refused a wrong and the default password (401); the compiled client read the
username from nzbget.conf and reached version/status/queue/history; strict
typecheck and the module's Dockerfile build pass.
