Add Hebrew and Urdu to the company language dropdown

Both lang/he.json and lang/ur.json shipped as empty Crowdin stubs but never made it into config('invoiceshelf.languages'), so admins could not pick either locale even after the matching font packages (noto-sans-hebrew, noto-naskh-arabic) landed in commit 04952d91. Add the two entries with native names (עברית, اردو) following the existing Svenska / ไทย / Tiếng Việt convention for non-Latin scripts.

Inserted alphabetically by English name — he between Greek and Hindi, ur after Ukrainian. The first PDF render for either locale will trigger ensureFontsForLocale() and synchronously install the corresponding font package; the UI itself stays mostly English until the Crowdin translations catch up, which is the intended trade-off — these locales are useful primarily as language tags for PDF rendering of Hebrew / Arabic-script customer data.
