Dhivehi localization and RTL

Every user-facing string is translatable, with lang/en and lang/dv
Real Dhivehi translations; uncertain ones are listed for human review
Views and components work in RTL (logical utilities only) and free-text inputs support Thaana
Tests use Thaana for user-facing behaviour

Done on main.

Every string is in lang/en and lang/dv: editor.php for the editor UI (sent in the editor config) and strings.php for block names, attribute labels, options and validation messages. The JS has the default config in both locales, generated from PHP and checked in CI.
The Dhivehi is real. Terms a native speaker should check are listed in docs/advanced-usage/translations.md#needs-review.
RTL: logical CSS only, a mirrored toolbar, menus and handle, and direction-aware columns. Inputs that take Dhivehi type Thaana.
Tests use Thaana for user-facing behaviour (rendering, validation messages, fields, Thaana typing).
