container: src: finance: change visidata default dir

The container environment's $DOCKER_FINANCE_CONTAINER_CONF is
bind-mounted and, by default, points to ~/.config/docker-finance.d

The parent dir (~/.config) is subsequently owned by root (Docker-ism).
Ergo, with visidata v3.2, visidata cannot create its default dir:

    "PermissionError: [Errno 13] Permission denied: for visidata config"

This commit fixes that by setting visidata's default dir to use the
calling profile's docker-finance.d (where profile customization occurs).

Also included is some related refactoring.
