feat: add Capture Region to Clipboard button action (#296)

* feat: add Capture Region to Clipboard button action

* feat: add Capture Region locale entries for all languages

* fix: merge identical Screenshot/CaptureRegion match arms (clippy)

On Linux and Windows, Screenshot and CaptureRegion dispatch to the same
native shortcut (Print Screen / Win+Shift+S), so clippy::match_same_arms
flagged the duplicated arms under -D warnings. Merge each pair with a
single | pattern. macOS keeps distinct arms (region uses a different
shortcut). No behavior change.

* fix: merge Screenshot/CaptureRegion icon arm (clippy match_same_arms)

The icon picker mapped both Screenshot and CaptureRegion to camera.svg,
which clippy::match_same_arms flagged under -D warnings in the workspace
clippy run. Merge into a single | pattern. No behavior change.
