I18N: Add translator context to "Scale" strings in image editor

[sanketio]

Summary

The word "Scale" appears twice in wp-admin/includes/image-edit.php with two distinct grammatical roles but both used the same esc_html_e( 'Scale' ) call with no translator context. In many languages (e.g. German: Skalierung vs. Skalieren), a noun and a verb require different translations, so translators were forced to pick one form for both usages.

Changes

File: src/wp-admin/includes/image-edit.php

Replaced both esc_html_e( 'Scale' ) calls with echo esc_html_x() to preserve HTML escaping while adding disambiguating context:

Location	Role	New call
Toolbar toggle button	Noun — panel section label	echo esc_html_x( 'Scale', 'noun: label for the image scale controls panel', 'default' )
Primary action button	Verb — executes the scaling	echo esc_html_x( 'Scale', 'verb: button to apply image scaling', 'default' )

Note: esc_html_e() echoes directly. WordPress core has no esc_html_ex() equivalent, so echo esc_html_x() is the correct pattern to preserve both HTML escaping and add translator context.

Testing

• No existing tests required updating. The only test file covering this area (tests/phpunit/tests/ajax/wpAjaxImageEditor.php) tests PHP save/restore logic, not HTML template output.
• English output is unchanged — esc_html_x() returns Scale in English exactly as before.
