chore: bump JS dependencies to latest minor/patch versions

Bumps within existing semver ranges (no majors):
- @types/jquery 3.5.20 -> 3.5.34
- @wordpress/scripts 26.13.0 -> 26.19.0
- grunt 1.6.1 -> 1.6.3
- grunt-wp-i18n 1.0.3 -> 1.0.4
- @wordpress/block-editor 12.10.0 -> 12.26.0
- @wordpress/components 25.8.0 -> 25.16.0
- @wordpress/dom-ready 3.42.0 -> 3.58.0
- @wordpress/hooks 3.42.0 -> 3.58.0
- @wordpress/i18n 4.42.0 -> 4.58.0
- @wordpress/icons 9.33.0 -> 9.49.0
- react 18.2.0 -> 18.3.1

Verified: npm run compile (css/js/mo) and npm run plugin-zip succeed.
lint:js/lint:css pre-existing failures confirmed unchanged (present
identically on main via git stash comparison) - not caused by this bump.

Remaining outdated packages are all majors (react 19, @wordpress/*
next-majors, jquery 4, @types/jquery 4) - left for a separate PR.
