Bump Compose BOM and Paparazzi, drop the snapshot diff threshold, re-record goldens (#1795)

* Bump Compose BOM and Paparazzi, drop the diff threshold, re-record goldens

- androidxComposeBom 2024.11.00 -> 2025.08.01 and paparazzi 1.3.4 -> 1.3.5, matching the chat SDK.
- Remove MAX_PERCENT_DIFFERENCE: the 0.5 threshold only existed because Paparazzi 1.3.4 antialiased fonts differently between macOS (recording) and Linux (CI verification). Paparazzi now runs with its default threshold.
- Re-record all 159 goldens. Paparazzi 1.3.5 names snapshot files with underscores instead of spaces, so every file is deleted and re-added. The new images are pixel-identical to the old ones; the BOM bump caused no visual change.

* Make the snapshot suite deterministic and cover both palettes per test

The preview call's duration flow emits its first value after a one
second delay, so the first test in a class captured either the title or
"0s" in the call app bar, depending on JVM warm-up. previewCall now keeps
the duration flow collected and waits for its first value once, so every
composition sees the same value.

Snapshot structure:
- Full screens use two files (light and dark); the two-half helpers are
  for components only, since a full-screen composable takes the whole
  height and hides the second half. Applied to the call participants
  list.
- The two-half helpers take a background color, used by the livestream
  overlay test to stand in for the video it is drawn over.
- The livestream backstage pair is merged into one two-half snapshot.
- The deprecated CallContent overload gets its dark variant.
