fix: reject invalid orientation values

[mrousavy]

Summary

• make CameraOrientation(interfaceOrientation:) failable and return nil for UIInterfaceOrientation.unknown
• make Android CameraOrientation.fromDegrees(...) return null outside the documented 0..359 range
• use explicit, non-overlapping degree buckets so invalid values cannot silently become UP
• handle nullable conversions explicitly at all iOS and Android call sites

Stacking

This PR is based on #4150 and should merge after it.

Validation

• ktlint on the changed Kotlin files
• swift format lint on the changed Swift files
• git diff --check
• native iOS and Android builds intentionally left to CI
