The root logger previously had no handler at all, so every module's logger.info() call (user creation, claims, password resets, ...) was silently dropped, not just unviewable. Adds a RotatingFileHandler writing into the existing /data volume so log content also survives container restarts/redeploys, plus /admin/logs (tail + line-count picker + full-file download) alongside the existing Users & Frames admin page.

"""Root-logger configuration: a rotating file handler under the same
|
|
/data volume as the sqlite DB and legacy config.json, so the admin log
|
|
viewer has something to read and log content survives container
|
|
restarts -- a redeploy happens on every push to main touching
|
|
server/**, which would make an in-memory-only log buffer nearly
|
|
useless in practice. Before this, the root logger had no handler at
|
|
all, so every module's logger.info() call (user creation, claims,
|
|
password resets, ...) was silently dropped rather than merely
|
|
un-viewable -- this fixes that too, not just adds a viewer."""
