Use Surface.ROTATION_0 for the camera targetRotation fallback

[replicant1]

ImageCapture.targetRotation is annotated @RotationValue, so a bare 0 literal trips lint's WrongConstant:

Error: Must be one of: Surface.ROTATION_0, Surface.ROTATION_90,
Surface.ROTATION_180, Surface.ROTATION_270 [WrongConstant]

Surface.ROTATION_0 is the same value and states the intent.

Scope

Covers two of the four affected sites — BlisterCountScreen and ScanScriptScreen. Two remain and are not fixed here:

• CountTabletsScreen.kt:257 — same ?: 0 pattern, a straight swap, just untouched by the work this was split from.
• CameraCaptureScreen.kt:176,178 — assigns from a rotation variable rather than a literal, so it likely needs @RotationValue on the source rather than a constant swap. I didn't want to guess at that one.

So lintDebug still fails on main after this merges. Worth a follow-up that clears the remaining two and gets lint back to green, at which point it could go in CI.

Verification

assembleDebug passes. No behaviour change — Surface.ROTATION_0 is 0.

Split out of the string-externalisation branch (#147), where it had been mixed in with unrelated work. Branches off main and is independent of it.

Pull request overview

This PR replaces the 0 literal fallback used for ImageCapture.targetRotation with Surface.ROTATION_0 in two camera-backed screens, aligning with the @RotationValue/WrongConstant lint requirements while keeping the same runtime behavior.

Changes:

• Replace ?: 0 with ?: Surface.ROTATION_0 for imageCapture.targetRotation in ScanScriptScreen and BlisterCountScreen.
• Add the required android.view.Surface import in both files.

File	Description
app/src/main/java/com/example/aitoui/scan/ScanScriptScreen.kt	Uses Surface.ROTATION_0 instead of a bare 0 for targetRotation fallback to satisfy @RotationValue lint expectations.
app/src/main/java/com/example/aitoui/inhand/blister/BlisterCountScreen.kt	Same targetRotation fallback adjustment, plus Surface import, to avoid WrongConstant lint warnings.
