fix(android): remove duplicate TextAlign import in InCallScreen.kt

Pre-existing build breakage on feat/desktop-audio-rewrite @ 8ceb6f4 —
TextAlign was imported twice (line 5 and line 50), causing Kotlin
compilation to fail with:

  e: InCallScreen.kt:5:39 Conflicting import, imported name 'TextAlign' is ambiguous
  e: InCallScreen.kt:50:39 Conflicting import, imported name 'TextAlign' is ambiguous

The line-5 copy was squeezed into the middle of the foundation.* block
(alphabetically out of place) — an accidental extra paste. The line-50
copy sits in the correct alphabetical position. Removed the former.

This blocks the APK build for the opus-DRED-v2 rebase. Unrelated to DRED
itself but the error surfaced because the cherry-picked phases caused
a clean Gradle build (no UP-TO-DATE short-circuit) that re-compiled
InCallScreen.kt against the fresh class graph.

Also noting that the previous working APK (unridden-alfonso.apk) was
built from the stale d0c1731 baseline which didn't have this bug —
one more reason the stale-branch build problem went unnoticed until
the opus-DRED-v2 rebase forced a clean Gradle pass.
