fix(settings): RTL Tabs + Hebrew labels (סביבה/כלים/בלוקים/רישומים)

Radix Tabs defaults dir to 'ltr' if not set explicitly, which broke
RTL inside Tab content (cards flowing left-to-right). Set dir='rtl'
on the Tabs root and translate trigger labels to Hebrew (kept
Paperclip in English as a brand name).
