slides(tappaas): restore the commit graph, and small corrections

The graph replaces the prose slide that stood in for it — annotated with the
vacation that explains the Sept/Oct 2025 flat spot, and regenerated so August
runs to the 25th (126). Keeps the one line worth saving from the slide it
replaces: the services stayed up through the flat bits.

Also: "every commit" rather than "every line" on the never-push guardrail;
Home Assistant as the suggested first service; evaluation tier calls for two
disks.
