feat(am-dbg): add graphs, dashboards, and others

[pancsta]

• feat(am-dbg): add graph rendering
• feat(am-dbg): add zellij dashboards
• feat(am-dbg): add auto narrow layout and --view-narrow
• feat(am-dbg): add --view-rain, --view-timelines
• fix(am-dbg): ignore ID-less clients
• fix(am-dbg): fix expand/collapse of schema pane
• feat(am-dbg): improve the toolbar

Dashboard can be started with task am-dbg-dashboard. The responsive narrow layout is useful also outside of dashboards. Requires zellij.

Graph rendering has been extracted from the am-vis prototype - automatic generation with 3-level of details of the currently selected machine is now built right into the toolbar.

Generated structure inside --dir:

# currently visible machine
MACHID.d2
MACHID.mermaid
MACHID.svg
# symlink for autorefresh
am-vis -> MACHID.svg
# overall map
am-vis-map.d2
am-vis-map.mermaid
