game-views ATLAS: mirror SCROLL log styling (strikethrough) + honour the redact filter

The merged ATLAS feed now reads its provenance rows the way SCROLL does:

- Struck (retracted/redacted) logs carry the strikethrough — buildAtlasFeed captures the source .drama-event-body.struck state and renderAtlasRow re-applies it as .atlas-row-body.struck (styled to match .drama-event-body.struck).
- A log hidden by the SCROLL Frame/Redact gear filter (display:none) is skipped in the ATLAS merge too — buildAtlasFeed checks getComputedStyle(ev).display, so unchecking Redact on SCROLL keeps those rows out of ATLAS.
- Also lays the source-toggle seam: atlasSources() reads the (forthcoming) ATLAS gear's view-checkboxes (scroll→provenance, post→post), defaulting to both when absent.

Verified: Jasmine renderAtlasRow struck spec + two FTs (struck row shows struck in ATLAS; redact-filtered rows absent from ATLAS) + the existing atlas aggregate FT, all green.
