Epic: In-game integration & live data

[ApocDev]

Tighten the loop between the running game and the app: complete the in-game planning surface, expose richer live state, and jump from an in-game selection straight to the relevant plan.

Sub-issues, in intended order:

• Mod UI: design pass and completion of the in-game panel #109 — finish and redesign the in-game panel.
• Summary panel: make the production matrix fill a wider window #4 — make the summary production matrix fill a wider window; delivered as part of Mod UI: design pass and completion of the in-game panel #109.
• Select a machine in-game -> focus its block(s) in the web #3 — select a machine in-game to focus its block(s) in the web app.
• Force bonuses panel: sync and display infinite-tech effects #137 — sync and display force-level infinite-tech effects.
• Live-data alerts: flag blocks running below plan #88 — flag blocks running below plan without requiring stored history.
• Time-series metrics (Prometheus-style) for live factory data #2 — retain and graph time-series factory metrics.

The lightweight alerts in #88 should ship before the larger time-series system in #2.
