fix(web): stop dumping the config and request headers to the journal

save_main_config logged its entire POST body and the full request headers at
ERROR on every save. The body is the configuration itself, and the headers
carry the session cookie, so a routine settings change wrote both to the
journal -- at a level that guarantees they survive any sane log filter.

The lines are leftover debug output: they say "DEBUG:" in the message while
calling logging.error, and they went through the root logger rather than the
module logger, bypassing the level configured for this blueprint.

Replaced with a debug-level line recording the shape of the request, which is
the part with diagnostic value. The local `import logging` went with them; it
shadowed a module-level import that was already there.
